Authorities in Bucks County are searching for a person of interest in connection with a double homicide in Northampton Township. The victims have been identified as Tyler and Christine Roy.

Police are seeking Daniel Kenneth Mooney, 26. Mooney is a neighbor of the Roys, First Assistant District Attorney Greg Shore said at a noon press conference.

Shore said Mooney may be walking with a pronounced limp. An arrest warrant has been issued for Mooney in connection with an unrelated car theft on April 30.

Here is another image of Mooney:

Authorities say a car belonging to the Roys was taken from the scene at 26 Kitty Knight Drive, and later found in Northeast Philadelphia. Anyone who sees Mooney should not approach him. "We believe he may be armed and certainly is dangerous," Shore said.

Authorities also released this image of the Roys:

Shore said he could not comment on how the couple were killed. A rifle and shell casings were found inside the home, but it's not clear at this time that those items have any connection with their deaths.
