BOULDER, Colo. -- A Lakewood man was arrested Tuesday after a handgun was matched to him in connection to a triple homicide in Coal Creek Canyon, the Boulder County Sheriff's Office said.

Garrett Coughlin, 24, has been charged with three counts of first-degree murder after deliberation, three counts of first-degree murder during the commission of a robbery and aggravated robbery.

The people who were killed -- Wallace White, 54, Kelly Sloat-White, 56, and Emory Fraker, 39 -- were found April 15 in the home in the 800 block of Divide View Drive.

All three had been shot, the sheriff's office said.

Friends of the homeowners called authorities, saying they had not heard from them in weeks. On a welfare check, deputies found the three bodies.

Investigators also found a large stash of marijuana plants.

Detectives were able to narrow the deaths by matching a gun Coughlin owned to the homicides, according to an arrest report.
