GOSHEN, Ind. (AP): Prosecutors say the December deaths of a northern Indiana man and his two teenage daughters found fatally shot in a home have been ruled a murder-suicide.

Evidence showed that 47-year-old Jeffrey Marvin fatally shot his daughters – 18-year-old Lexis and 15-year-old Haley – and then himself several days before their bodies were found on Dec. 18.

Elkhart County officers were dispatched to the home for a welfare check after no one had heard from Marvin or his daughters for several days.

Investigators determined that Marvin “had a motive, and did kill his two daughters” before he then took his own life.
