Jacob Daniel Price entered the lobby of the Crestview Police Department building in the early hours of Wednesday morning with blood on his shirt, the Okaloosa County Sheriff’s Office said in a news release. The 30-year-old arrived shortly after 4 a.m. and told officers that he had shot his mother and father as well as two family dogs at their home, the sheriff’s office said.

Deputies from the sheriff’s office went to Price’s residence on Equine Drive, which is located north of Crestview, Florida. They found Price’s parents Jolene Price, 51, and 56-year-old Robert Price dead inside the master bedroom of the house.

Both of them appeared to have sustained gunshot wounds to the head, the Northwest Florida Daily News reported, citing the arrest report.

Two dead dogs were also found at the house as well as two German Shepherds who were not harmed. One of the dead dogs was found in the bed with the victims while the other was dead on the dining room floor, the Daily News reported. Both appeared to have been shot.

The two German shepherds were handed over to the Panhandle Animal Welfare Society (PAWS). A family member will be taking the surviving dogs in, according to the Daily News. Newsweek has contacted PAWS for further comment.

Price has been charged with two counts of premeditated murder and two counts of aggravated animal cruelty, the sheriff’s office said. Autopsies on Jolene Price and Robert Price will be carried out by the First Judicial Circuit Medical Examiner’s Office, according to the sheriff’s office.

Sheriff’s deputies said the motive for the incident is still being investigated. Price had been living at the residence with his parents at the time they were killed, sheriff’s office spokeswoman Michele Nicholson said, according to the Daily News.

He served as a field radio operator in the U.S. Marine Corps from 2009 until 2013, the newspaper reported, and was deployed abroad twice between 2010 and 2011 under Operation Enduring Freedom, the U.S. government’s official name for the war on terror in response to the September 11 attacks.

But a Marine Corps spokeswoman told the Daily News that he left while still at the rank of private because the character of his service was “incongruent” with the standards expected by the Marine Corps.

Newsweek has contacted the Marine Corps for further comment.
