Kouri Richins slipped five-times the lethal dose of fentanyl into a cocktail that Eric Richins drank in the false hope of inheriting his estate worth more than $4m (£3m) in Utah in March 2022, prosecutors said.
They said Richins, an estate agent, was deep in debt and planning her future with another man.
She had opened numerous life insurance policies on her husband without his knowledge, with benefits totalling about $2m, prosecutors said.
The internet search history from Richins's phone included "what is a lethal.dose.of.fetanayl" and "luxury prisons for the rich America", a digital forensic analyst said.
Prosecutor Brad Bloodworth played a clip of Richins's 911 call from the night of her husband's death in court.
That's "not the sound of a wife becoming a widow", he said, quoting the defence's opening statement.
"It's the sound of a wife becoming a black widow."
Defence lawyer Wendy Lewis said the prosecution "looks at facts one way and sees a witch, but if you look at those facts another way, you see a widow".
The defence team argued Eric Richins was addicted to painkillers and asked his wife to procure opioids for him.

Richins, 35, stared at the floor and took deep breaths as she was convicted of aggravated murder on Monday.
She was also convicted of other felonies, including attempted murder for trying to poison her husband weeks earlier on Valentine's Day with a fentanyl-laced sandwich that made him black out.
Jurors also found Richins guilty of forgery and fraudulently claiming insurance benefits after his death.
Shortly before her arrest in May 2023, Richins self-published a book for children about coping with the loss of a parent.
Prosecutors argued she planned the killing and tried to cover it up.
She will be sentenced on 13 May - the day her husband would have turned 44.
In a witness statement to the Royal Courts of Justice in London on Tuesday, Mr Adams said he was "never a member of the IRA or its Army Council" and denied involvement in any bombings in the UK.
The former leader of Sinn Fein said the allegations brought against him in a civil claim, that he was responsible for three bombings in Britain during the 1970s and 1990s, were "untrue".
Mr Adams, one of Northern Ireland's best-known political figures, has long been accused of having been a member of the Provisional IRA. He has always denied the allegation.
The 77-year-old wished the judge a "very happy St Patrick's Day" as he entered the witness box.
"I was never the commanding officer, or OC of the 2nd Battalion of the IRA's Belfast brigade," Mr Adams said in his 20-page statement.
"Indeed, I have never held any rank or role within the IRA, including on the IRA's Army Council.
"I have never held a command-and-control role in the IRA, and have never been a senior, let alone most senior figure, in the IRA."
The legal case was brought by three people who were injured in three different bombings: one at London's Old Bailey court in 1973, the Provisional IRA's first such attack on the British mainland, and two 1996 blasts, targeting London's Docklands and Manchester.
The claimants are seeking a finding on the balance of probabilities that Mr Adams is personally liable as a senior member of the IRA, and are claiming £1 in damages.
However, Mr Adams denied any role in the bombings, telling the court: "To be clear, I did not sanction any bombings in Britain in March 1973 - or in any other year."
He added: "Sinn Fein is a political party that seeks a whole range of political objectives, including an end to partition and Irish unity.
"Throughout my life, opponents of Sinn Fein have repeatedly sought to conflate Sinn Fein with the IRA. As I have always stated, Sinn Fein and the IRA are separate organisations."
Sir Max Hill KC, representing the bombing victims, said the Provisional IRA had caused 1,178 deaths, and asked Mr Adams: "The business of the IRA was deadly. We can agree on that, can't we?"
Mr Adams replied: "Well, the business of the IRA was to resist armed British occupation and aggression in the part of Ireland that I lived in."
He added: "Against them was the British Army; there were a number of armed groups who were deadly."

Sir Max accused Mr Adams of having family in the IRA, mentioning his father who was charged with the attempted murder of two police constables in Belfast in 1942, and his uncle who was a member of the "old IRA".
Mr Adams said: "Well, of all the things we have to take responsibility for, we do not have to take responsibility for our fathers".
Sir Max also alleged Mr Adams used bombings to force the British government to the negotiation table.
Mr Adams replied: "No. We put together a peace process. It was given to John Major's government, if I may use the expression, on a plate."
He also denied Sir Max's accusations that he represented the IRA at talks with the British government at Cheyne Walk in 1972, telling the court he represented Sinn Fein.
In response to questions about his arrest in 1973 alongside three IRA volunteers, Mr Adams said he had "no knowledge" of them being members of the group.
When asked if he stood by the actions of the IRA, Mr Adams said: "I do not stand by everything that they did, but these were my neighbours".
Mr Adams said, though he was retired from frontline politics, he was committed to efforts to "cement the peace process, and to promote Irish unity".
"My political work, from the late 1960s until today, is a matter of public record, and widely reported," he said. "I worked with many others over many years to bring the conflict in the north of Ireland to an end."
The court case continues.
Here are four:
Inconsistencies over discussions with the Iranians
The US president has said a few times over recent hours that dialogue with the Iranians is ongoing.
"They want to make a deal," he said on the plane back to Washington DC on Sunday night, repeating it again on Monday.
But when asked the obvious questions - "Who are you talking to that wants to make a deal?" and "what does a deal look like?" - the president couldn't answer.
Instead, he said that all the people they had been talking to were now dead. He's said this before, attributing it, bizarrely, to the military operation being so successful.
He also mused whether he would actually want to make a deal with the Iranians even if they wanted to. These musings were peppered with "they want to make a deal".
Artificial Intelligence
The president revealed that he had seen a video (presumably on social media) which showed the US aircraft carrier, the Abraham Lincoln, under attack and on fire.
He then revealed that he'd called his generals and asked: "What's with the Abraham Lincoln? Looks like it's on fire."
He was then told it was fake.
This raises serious questions about the sort of content the president is absorbing and believing on social media.
The Starmer call
The president and prime minister spoke by phone on Sunday. The "readout" of the call from Downing Street was thin and revealed very little. A source later told me that the call was "good" and that there was a "clear shared interest in keeping the Strait of Hormuz open".
I am told that any public frustration shown by the president was not reflected in the call.
The president has now revealed a further window into that call.
"You know the prime minister of UK - United Kingdom - yesterday, told me, 'I'm meeting with my team to make a determination'."
"I said, 'you don't need to meet with the team. You're the prime minister. You can make your own… why do you have to meet with your team to find out whether or not you send some mine sweepers to us…'"
Learning about Lebanon
In another moment of conscious thought, he revealed that he'd only recently been told about the geographical power structure in Lebanon - something that's vital to understand given the Israeli military operations the US is supporting there right now. In the same sentence, he also expressed surprise that people lived even in Ukraine or Lebanon.
This is the verbatim transcript of that moment: "...substantial person, wealthy person, whose parents live in Lebanon. I said: 'Really, how do you live in Lebanon? Your parents? Oh, yeah, they live there. And over the years, they've gotten used to the fact that it's being bombed.'
"But they explained to me that it's really a different section of Lebanon. It's the section where Hezbollah is, and they get used to it, I guess... I mean people live in Ukraine.
"You would think they wouldn't live in Ukraine, but they live in Ukraine. I don't know that I'd do that, but they live in Ukraine. They live in Lebanon."
Self-described misogynist Andrew and his brother have been posting photos and videos of their time in Hong Kong since arriving over the weekend.
Politics latest: Regional leaders to gain 'control of a share of some national taxes'
Both the UK and Romania have extradition warrants against the pair as they face charges in each country, including rape and human trafficking. They both deny all charges in both countries.
But Hong Kong politicians said that they could only extradite the British-American brothers if the UK or Romania requested Hong Kong does so.
The Conservatives and Liberal Democrats have now called on Home Secretary Shabana Mahmood to urgently demand their extradition.
Andrew Tate taunted the UK government on Monday, posting on X: "If England doesn't extradite me soon I'll have to fly there myself and I think the taxpayer should pay for my flight if the government wanna talk to me so badly."
The social media posts the brothers have shared from Hong Kong, liked by thousands, include a video showing teenage boys flocking to take selfies with the pair in the city's famous Lan Kwai Fong bar district.
They also shared videos of them partying in various bars with lots of women around them and on a luxury yacht as well as a photo underneath the Marsh Road sign in Wan Chai in reference to the Luton council estate they grew up on, and a picture of controversial shark's fin soup.
Conservative shadow home secretary Chris Philp told Sky News: "The Tate brothers faces serious criminal allegations in the UK, it is important justice is done.
"The government should urgently send an extradition request to Hong Kong so that the Tates can be brought back to the UK to face justice. The home secretary, Shabana Mahmood, should do this urgently."
Lib Dem home affairs spokesman Max Wilkinson told Sky News: "Andrew Tate is a despicable and cowardly thug who has been accused of some of the worst crimes possible.
"The government must not just sit back and allow this dangerous man to hide away from justice on the other side of the world.
"They must urgently demand the extradition of both Andrew Tate and his brother."
The UK suspended its extradition treaty with Hong Kong in 2020 after Beijing introduced a national security law on the city, but the UK government last year proposed reinstating some form of extradition cooperation on a "case-by-case basis".
Hong Kong lawmaker Joe Chan Cho-kwong, a former police officer, told the South China Morning Post: "There are still mechanisms as they could reach out to Hong Kong police through Interpol.
"If the UK and Romania do not do so, there is nothing that Hong Kong Police can do."
Andrew and Tristan Tate are facing 21 charges in the UK, including rape, actual bodily harm and human trafficking, as well as a civil case for alleged tax evasion.

They had a travel ban placed on them by Romania, where they are facing criminal and civil investigations with charges including human trafficking and forming an organised crime group to sexually exploit women. Andrew is also facing a rape charge.
The ban was lifted after two years in February 2025, and they flew via private jet to Florida. They have lived in Dubai, Florida and Romania since then.
A Home Office spokesperson told Sky News: "We are fully committed to making sure violence against women and girls is treated as the emergency it is.
"As a matter of long-standing policy and practice, the UK will neither confirm nor deny that an extradition request has been made or received. Given the ongoing Romanian investigation, it would be inappropriate to comment further."
Jay Cartmell, eight, suffered a serious head injuries in the incident, which happened on land near Warcop, Cumbria, on 28 September 2024.
The boy, from Frizington, Cumbria, was taken to hospital by air ambulance, and was later pronounced dead.
Cumbria Police said in a statement on Tuesday that Allan Thursby, 64, of Cleator Moor, had been charged with gross negligence manslaughter.
The force said that he was arrested on the day of the incident, and has been on police bail since then.
Thursby has been bailed to appear at Carlisle Magistrates' Court on 26 March, police added.

In a statement, Jay's parents, Leigha and James Cartmell, described their son as the "third corner of our beautiful family triangle" who was "loving, kind and full of mischief".
"Jay was extremely loved not only by us, but by all who met him", they added. "He had fantastic friends, and always had a smile on his face.
"We will miss him every day, but his love surrounds us and his memory will never fade."
