BLISSFIED, Mich.(WXYZ) - Michigan State Police are looking for a man they believe murdered two women from Lenawee County.
The victims have been identified as 34-year-old Amy Merrill and her 24-year-old sister Lisa Gritzmaker.
Gritzmaker was 8-months pregnant.
Investigators say they were shot and killed inside Merrill's Blissfield home Friday night.
Their mother, Robin McGowan, was also shot but survived.
The suspect is 38-year old Thomas Jack Fritz of Sylvania, Ohio. He is a white male, 5' 9", weighs 186 pounds and has brown hair and blue eyes. Police say he had been the boyfriend of Merrill and the couple had been living together.
Family members say Amy ended the relationship a few weeks ago. They had one son together.
Merrill also had two other sons. Gritzmaker had two daughters and a third girl on the way. The baby's name was to be Abigail.
State Police tell Action News an argument developed which led to the shooting.
Family members tell Action News that Gritzmaker and McGowan went to the home when they didn't hear from Amy. A family friend who was parked nearby heard three gunshots.
Fritz is believed to be driving a 2002 maroon, four-door Honda with Ohio license plate EQP 8075.
He is considered armed and dangerous according to State Police.
If you see him, you're asked to not approach him and contact the Michigan State Police immediately at (517) 241-8000.
