Read full list of Lindsay Clancy's Google searches in final weeks before she killed her children: Haunting evidence gives clearest picture yet

'Where is the carotid artery.'

'How to slit your throat to die.'

'Can you turn airbags off Kia Sorento.'

Four days after making those disturbing searches on her phone, Lindsay Clancy would attempt to kill herself after strangling her three children.

But it was what she searched the day before that could prove even more significant to her defense.

On January 19, five days before the killings, Clancy googled 'hallucinations,' 'psychosis symptoms' and 'schizophrenia.'

Those searches could undercut one of the prosecution's central arguments: that Clancy only began claiming she was suffering from psychosis and hearing voices after the killings.

The mother-of-three also made multiple searches about the various drugs she was taking, after being prescribed a bevy of 13 medications by different providers.

But among the searches depicting her seemingly spiraling mental health, there were also signs of normal life, with Clancy searching for 'organic baby food' and toys.

The searches appear to offer the clearest window yet into Clancy's state of mind in the days before she strangled Cora, five, Dawson, three, and Callan, eight months, in the basement of their home in the wealthy community of Duxbury, Massachusetts.

She then cut her own wrists and neck and jumped out of the second-floor master bedroom window.

Clancy was paralyzed but survived to stand trial for her children's murders in a case that has both divided the nation and shone a light on postpartum mental health.

Clancy, who marked her 36th birthday inside the courtroom this week, does not deny killing her children.

She argues that she is not guilty by reason of insanity because she was suffering from severe postpartum psychosis and depression.

Prosecutors argue she was of sound mind and planned and premeditated the killings.

The searches took center stage in Plymouth County Superior Court on Thursday, after a week in which jurors saw graphic autopsy photos, heard Clancy's desperate messages to her doctor and watched her break down in anguished sobs.

Clancy's text messages and digital notes were also shown to the court.

But it was the Google searches that painted the clearest picture yet of her suicidal thoughts and possible psychosis in the days before the killings.

Between December 2022 and January 2023, Clancy also searched terms including 'insomnia,' 'sleep,' 'bipolar' and 'postpartum depression.' 

She also made several searches for information about the 13 medications she had been prescribed by different providers as well as their side effects.

But the most striking searches came on January 19.

At 11.19am, just five days before the killings, Clancy searched for 'hallucinations.'

That same day, she searched 'psychosis symptoms,' 'schizophrenia' and 'On Seroquel [a bipolar drug] feel like I can't have a conversation.'

They could be significant for the defense, which is due to lay out its argument that she was suffering from postpartum psychosis when she killed her children next week.

Prosecutors have suggested that her claims of hearing voices emerged only after the killings, when she spoke with a psychologist hired by her attorneys.

Among the online searches and other cell phone records revealed in court, there was no mention of methods or plans to harm another person.

She wrote in her notes about feeling frustrated with her children, but the only apparent thoughts of violence were directed at herself.

Tim Chiappini, a cell phone forensics expert with the Massachusetts State Police, confirmed that he had found no searches for 'ways to kill' – a claim previously made by the prosecution and which Clancy's defense has filed a motion to strike.

The following day, on January 20, Clancy searched 'intrusive' – seemingly referring to intrusive thoughts – and 'can you treat a sociopath.'

She then made three searches that appeared to relate directly to suicide: 'Where is the carotid artery,' 'How to slit your throat to die' and 'Can you turn airbags off Kia Sorento.'

Clancy drove a Kia Sorento at the time.

Four days later, she attempted to slit her neck and wrists and jumped out of her second-floor bedroom after killing her children.

But there were warning signs earlier, too.

On December 29, she googled suicide.

Two days later, on December 31, she googled 'insomnia.'

On the same day she was looking up symptoms and information about her mental health, her searches also show she was juggling her duties as a mom.

There were searches for formula and baby food as well as searches related to her children's health – something that Clancy was anxious about – including 'child with bloated belly,' and 'UTI symptoms children.'

There were also searches for 'premade goody bags,' 'best kids movies,' 'Nova trampoline park,' 'unicorn picture,' 'unicorn picture coloring,' 'Paw Patrol,' and 'fluffy slime recipe.'

Cora's fifth birthday was coming up in early January and Clancy was planning her party.

In the early hours of New Year's Day, Clancy checked into McLean Hospital for psychiatric help.

She stayed for five days before being discharged in time for Cora's birthday – the final celebration the family-of-five would share.

An iPhone note presented in court offered another glimpse into Clancy's state of mind at the time.

Lindsay Clancy's murder trial: All the key stories

'I'm sad and depressed because I'm not able to parent my third child like my first. I want to treat every one of my babies like my first, but I know that's not a feasible possibility,' she wrote.

'I want to feel happy, but it would be nice to feel authentically happy and not fake.'

The jury also heard about an earlier search for 'suicide methods' made on Patrick Clancy's Surface Pro in August 2022.

Prosecutors say Lindsay made the search, while the defense argues Patrick accidentally accessed the page.

Patrick previously testified that he may have inadvertently reached it while searching for country singer Tom T. Hall, who died by suicide.

The search was made before Clancy began seeking treatment for postpartum mental health issues.

Throughout the third week of the high-profile trial, wild conspiracies and theories have flooded social media.

But inside the courtroom, the focus has been firmly on more harrowing issues of suicide, mental health and the tragic deaths of three small children.

As the jury takes a three-day weekend, Judge William Sullivan reminded them to avoid the news and the noise.

But, just as importantly, he urged the 18 men and women handpicked to hear the gut-wrenching case, to take care of themselves: 'Relax the best you can.'
