UPDATE -- An infant and its parents are dead in an apparent murder-suicide in New Market, Frederick County officials have confirmed.
A 5-year-old was at home in the 6800 block of Woods Court at the time of the murder, but she was able to get out of the home and run to a neighbor's house. The neighbor called 911 at about 8:15 p.m.
The Frederick County Sheriff's Office is currently not releasing the names of the victims, although the deceased appear to be a mom and dad, Capt. Tim Clarke said.
"We believe that the child was in the home, and then at some point left and went to the neighbor's and asked for assistance," Clarke said.
The 5-year-old girl was the only survivor.
Authorities said all three victims were shot. The 5-year-old girl, however, was not injured. She is now with child protective services.
Police are in the process of notifying next of kin.
