Autopsies have confirmed that an elderly Brookings couple found dead in their home died of gunshot wounds, authorities said Friday.

Curry County District Attorney Charlie Steak said he could not comment on what kind of gun was used, or how many times the victims were shot or where. He also declined to say where in the home the bodies were found or how the killer entered the home.

No charges have been filed and no prime suspect has been named at this time, Steak said.

Gregory Arthur Hoenshell, 21, the couple's grandson, remains a person of interest, he said.

Hes the only person who the Brookings Police Department has stated is a person of interest, he said.

The bodies of Dorothy Hoenshell, 72, and Edward Hoenshell, 77, were discovered on Monday by a real estate agent entering their home at 717 Fourth St.

Police responding to the scene immediately cordoned off the house and began searching for the grandson, who was reportedly last seen driving the couples car before their bodies were found.

Hoenshell was arrested in Crescent City on Tuesday. The couples car had been found there the night before, police said.

Hoenshell is currently being detained in the Del Norte County Jail on five Del Norte County warrants unrelated to the murder. Those warrants charge cruelty to a child, assault and battery, cruelty to animals, forgery, resisting arrest and burglary.

He is scheduled to go before a Del Norte County judge on those charges on April 26.

Meanwhile the Brookings Police Department is continuing its investigation, Steak said.

Police request that anyone who saw Hoenshell between April 8-10 contact Detective John Bishop at the police department at (541) 469-3118.

At the request of Steak, the Oregon Department of Justice will assist with the investigation.

Steak said he expects an investigator from the department to arrive next week.
