The husband and wife, who police say are in their late 20s, were found on the second floor of the house. Police said they were murdered some time between 10 p.m. Monday night and 10 a.m. Tuesday morning.
A suspect has not yet been identified.
Police found a rifle and shell casings inside the home though they have not determined whether the rifle was used to kill them, Clark said.
There was no forced entry into the home, but neighbors reported hearing suspicious activity Monday night.
One neighbor told NBC10 they heard the sound of a car alarm outside the couple's home around 10 p.m. Monday. Police discovered Tuesday that a car belonging to one of the victims is missing. They have not yet released a description of the vehicle.
Police have not responded to the home previously, Clark said, adding that it is a quiet neighborhood.
"We've had no contact with these folks at all," Clark said. "They seem to be a nice, young couple. Just happened to be unfortunate victims in this case."
Investigators spent hours scouring for clues in the roped off home as on-edge neighbors waited for more information.
"It's just scary because you just don't know the situation you don't know what happened," neighbor Joanna Kampf said.
