JOLIET, Ill. (AP) — Autopsies have determined that a Joliet man shot and killed his girlfriend and their two children before he fatally shot himself as police initially believed.

Joliet Police have said since Thursday that the deaths appeared to be murder-suicide and after the autopsies showed each victim died of a single gunshot. The (Joliet) Herald-News reports that autopsies conducted by the Will County Coroner’s office confirmed detectives’ suspicions.

Police found the bodies of 34-year-old Brandyn Lee, 28-year-old Jaquelon Gaskin, 6-yeer-old Gianna Lee and 1-year-old Giovanni Lee on Wednesday night in their home.

The investigation determined there had been no calls to police about “domestic issues” at the residence but police said evidence at the scene and witness statements led detectives to the conclusion that Lee killed the others before killing himself.
