Facebook memorial honors murdered sisters, Suspect still at-large

Amy Lynn Merrill (pictured on the right) and her pregnant sister Lisa Michelle Gritzmaker (pictured on the left) were both killed on Friday.

Authorities are still looking for the looking for their suspect in the murders of two sisters killed in Blissfield on Friday night.

On Monday, Michigan authorities made another plea to the public for help finding 38-year-old Thomas Jack Fritz.

A three-count felony warrant has been issued for Fritz in the murder of his former girlfriend 33-year-old Amy Lynn Merrill, the death of her pregnant sister 24-year-old Lisa Michelle Gritzmaker and the wounding of their mother 52-year-old Robin Lynn McCowan.

All three were found shot inside Merrill's North Lane Street home just before midnight.

Residents in the normally quiet community are still in shock that a crime like this could happen to their neighborhood.

"We realize now that tragedy can happen anywhere," a neighbor of the victims, Darlene Petee, said.

Someone has already created a Facebook memorial, to honor the victims, allowing others in the community to express their feelings on the murders.

Crime Stoppers of Lenawee County is now offering a cash reward for tips that lead to the arrest of the person responsible.

Authorities, however, warn that anyone who sees Fritz should not approach him since he is considered armed and dangerous.

Police believe Fritz may be driving a burgundy or maroon 2002 4-door Honda with the Ohio registration EQP8075.

Anyone with information on Fritz's location is asked to call MSP Operations at 734-242-3500.

Tipsters can also call Crime Stoppers at 517-266-6161 or 877-276-8477.
