Authorities say a Lynnfield man fatally shot his pregnant girlfriend and her sister before killing himself following an argument over the unborn child's name.
Essex District Attorney Jonathan Blodgett says police responding to the home the victims shared at about 10 p.m. on Monday night found the three bodies.
Blodgett says 51-year-old Joseph Cummings shot his girlfriend, 35-year-old Kimberly Nguyen, then shot 29-year-old Lilly Nguyen, before turning the gun on himself. Kimberly Nguyen was six-months pregnant with Cummings' child. The fetus also died.
Kimberly Nguyen's 12-year-old daughter fled to a neighbor's house to call 911. She is not Cummings' child.
Police recovered several guns from the home, including two apparently used in the shootings.
Autopsies are scheduled and the killings remain under investigation.
