Strouble faces charges of first-degree murder for what authorities describe as the deliberate killings of Jacob Q. Lambert, her partner and father of her children, along with his parents, Stacy and Patrick Forde.

Authorities reported that last month, Lambert was discovered dead in a vehicle parked in the driveway, while his parents were found deceased inside the residence’s first floor, near the main entrance, on East Norway Trail in Crete Township.

According to the sheriff’s office, Strouble allegedly made self-incriminating remarks following the killings, and a firearm recovered by police matched the weapon used in the crime.

Earlier, prosecutors suggested that Strouble’s motive for killing Lambert was rooted in dissatisfaction with his parenting style regarding their two children.

They said Strouble and Lambert were in his truck, when she offered to give him a massage.

Prosecutors say she then shot him in the head while he was face down.

Prosecutors claim she then drove to his mom and stepdad’s home, where she started shooting when they opened the door.

Patrick Forde was shot 17 times. Stacy Forde was shot three times.

Strouble was arrested at her parents’ Saint John, Indiana home.

She’s next due in court April 20.
