The Placer County Sheriff’s Office says, back on June 5, deputies responded to a 911 call at a residence in the Homewood area.

At the scene, 70-year-old Robert Gary Spohr was found dead. He had been shot, deputies say. Spohr’s wife, Wendy Wood, was also shot.

Deputies say the home where the couple was found had not been burglarized. There are also no signs of forced entry.

“We know that he died of at least one gunshot wound a search of a house did not reveal a gun, so any weapon that was used is still outstanding which is very suspicious,” said Lt. Nelson Resendes with the Placer County Sheriff’s Office.

No other details about what may have led up to Spohrs’ shooting have been released at this point, but on Thursday the sheriff’s office released surveillance video showing a person walking around the property at the time of the shooting.

The short clip shows a person in a hoodie, backpack, grey sweatpants, and a neck gaiter face mask running across a driveway.

“No reason to believe that this could occur at any other home. This does not appear to be a random wild act,” Lt. Resendes said.

The couple’s daughter issued a statement about the shooting. Click here to read it.
