SEE IT: What Lindsay Clancy Searched Online Days Before Killing Her 3 Children

Lindsay Clancy used her phone to search the phrase “can you treat a sociopath” just four days before she killed her three children and then attempted suicide, a Massachusetts State Police investigator testified Thursday.

Sgt. Timothy Chiappini told jurors that a forensic review of Clancy’s phone revealed that the search was made on January 20, 2023. In the weeks leading up to the January 24 killings, the phone was also used to search terms related to mental illness, including “bipolar disorder,” “postpartum depression,” “hallucinations,” “schizophrenia,” and “psychosis.”

Clancy is on trial for the murders of her three children, Cora, 5, Dawson, 3, and Callan, 8 months. She does not dispute killing them, but her attorneys argue that she had postpartum psychosis and was legally insane at the time. Prosecutors contend that Clancy deliberately planned the killings and understood what she was doing.

Under cross-examination Thursday, defense attorney Kevin Reddington questioned Chiappini about several other disturbing searches allegedly recovered from Clancy’s phone.

“Did you come across a search, ‘where is the carotid artery?'” Reddington asked.

“I don’t recall,” Chiappini replied.

Reddington also asked whether he’d found searches for “how to slit throat to die” and “how to turn airbags off on Kia Sorento,” but Chiappini said he could not recall those either.

“These all came from Lindsay’s phone, right?” Reddington asked as he held up posters showing blown-up screenshots of the searches.

Chiappini replied, “I can’t confirm that.”

“It’s a pretty good inference though, right?” Reddington pressed.

“Yes, sir,” was Chiappini’s response, and he noted that the phone number displayed on the screen matched the one he’d used for the forensic search.

Investigators also recovered notes from Clancy’s phone describing her struggles with motherhood and fears that she was failing her youngest child:

I am sad and depressed because I am not able to parent my third child like my 1st. I want to treat any one of my babies like my first, but I know that’s not a feasible possibility. I’m sad that I stopped breastfeeding. I feel not as connected with Cal now. I think I sort of resent my other children because they prevent me from treating Cal like my first baby, and I know that’s not fair to them. I know that.

Clancy also wrote that she had “fallen out of the habit of doing anything fun” and described being terrified that something would happen to her children or that she would make a mistake that negatively impacted their development.

“For the last 5 years, I’ve just filled my mind with all things parenting, and it’s just unhealthy,” she wrote.

State Trooper Kyle Pavao also testified on Thursday, stating that he’d reviewed a Surface Pro tablet and found searches for country musician Tom T. Hall — who died by suicide in 2021 — and stated that someone in the home had then clicked on a link that opened a page detailing “suicide methods.”

9:40 AM: The device accessed a Facebook profile page (Lindsay.969).

09:42 AM: A search was conducted on Spotify for the musician Tom T. Hall, leading to playing the song “That’s How I Got to Memphis” at 9:44:18 AM.

Other search terms included:

• What to do when a psychiatrist overprescribed
• Lamictal / “Zolafi” [Zoloft])
• Can bipolar disorder be temporary?
• Can benzos reveal bipolar disorder?
• What is mania?
• How long are detox programs?

Patrick Clancy, Lindsay’s former husband and the children’s father, previously testified that he was the person who searched for Hall because he wanted to listen to his music. He said he opened Hall’s Wikipedia page and accidentally clicked a hyperlink that took him to information about suicide methods.
