Another case of children being murdered in the United States carried out by a white American woman who happens to be their own mother

Massachusetts mother Lindsay Clancy looked up “ways to kill” before she strangled her three young children earlier this year, court records reportedly alleged.

The latest details in the grisly murder case against the 33-year-old mother were revealed in newly unsealed search warrant affidavits.

“Ms. Clancy used her cellular telephone and her journal to document her mental state and her feelings about her children, in addition to keeping track of her medications, and researching ways to kill, which means that [it] is reasonable to conclude that Ms. Clancy would have used all formats and tools available to her including a tablet,” one affidavit said, according to the Boston Globe.

Clancy allegedly used exercise ropes to strangle her three kids — Cora, 5, Dawson, 3, and 8-month-old Callan — inside the Duxbury home she shared with her husband in January.

The new court documents do not spell out specific internet searches, the newspaper reported.

The affidavits were used by authorities to request access to Clancy’s electronic devices, including her cellphone, tablet and laptops, the Boston Herald reported.

Clancy, whose attorney says suffered from postpartum psychosis, jumped out a second-story window following the attacks on her three children but survived the leap.

Her notebooks included a list of medications and thoughts of suicide, the court docs also said, according to WCVB.

Prosecutors have alleged that Clancy planned the Jan. 24 murder of her three children, while her defense team insisted she was suffering mental health issues and was overmedicated with prescription psychiatric drugs.

Clancy, who worked as a delivery nurse, remains in a medical facility with a new arraignment in Plymouth Superior Court set for Thursday.
