Adam Dees, 22, sat down with Ada County Sheriff’s Office detectives Monday, three days after he was sentenced to life in prison for killing three members of a Boise family in March.
Dees said he picked the house on Cartwright Road to rob in March because it wasn’t close to any roads or neighbors and it looked as though people who had money lived there, sheriff’s officials posted in a blog Monday evening. He wasn’t familiar with the residents, he said.
Dees told detectives that it wasn’t that difficult for him to kill three members of the Welp family because he had done so much killing in “first-person shooter” video games.
Ted Welp, 80; his wife, Elaine, 77; and their son Thomas, 52, were shot in the head and struck repeatedly with a wooden baseball bat late March 8 or early March 9 in their home atop a secluded hill off North Cartwright Road. Dees tied them up. He also stabbed Thomas Welp.

On Monday, Dees explained in detail that he committed the robbery and murders by himself. He also said it was his first and only home-invasion robbery, but he might have tried more in the future if he hadn’t been caught, the Sheriff’s Office reported.
He told detectives that he was depressed, suicidal and didn’t see his life going anywhere at the time, so he decided to “just go rob a house … that’ll give me money to play with for a while.”
Dees said he used Google Maps to search for remote areas around Boise and Mountain Home for high-end homes to rob. He settled on the area near Cartwright Road and used satellite maps to pick some possible targets.
He said he drove along Cartwright Road on March 8 and began looking around, dismissing some Foothills houses because they were too close to roads or other homes. Once he settled on the Welps’ residence, he said, he parked his car on a nearby street, hiked down a hillside and staked the home out while working on a plan.
He then drove to his Nampa residence, waited until it got darker and drove back to Cartwright Road, he told detectives. Dees said he wore black clothes and armed himself with guns and knives. He parked his car far away and hiked down the hillside again.
Dees said he first broke into a second house being built on the property and stole some power tools. He then moved over to the main house, where he found that a door to the garage was open, so he went inside and hid. He said he found a set of house keys inside a truck in the garage, which he used to get in the house. He saw a security system for the home was not armed when he went inside, he said.
Dees told detectives that if the security system had been turned on, he would have left immediately. He also said he probably would have given up on his plan if the family had a bigger dog, the Sheriff’s Office reported.
The killer’s debriefing with detectives Monday was one of the conditions of his plea agreement with Ada County prosecutors, which took the death penalty off the table.
Dees will serve three consecutive life sentences without the possibility of parole.
