The body found in Arrowrock Reservoir on Sunday has been identified as Mark David Levi Miller of Boise, according to Boise County Chief Deputy Coroner Mike Johnson. The cause of death is under investigation.
Miller, 47, is a suspect in a Boise Police Department arson investigation.
Miller’s body was found after dive crews located a Dodge pickup truck in Arrowrock Reservoir, according to Boise County Chief Deputy Dale Rogers.
Two men spotted the pickup underwater while paddle boarding in the reservoir Sunday afternoon. The two contacted a marine deputy in the area, and the incident was called into dispatch around 2:45 p.m., Rogers said.

Boise County deputies, emergency personnel and a dive team were called to the scene near Milepost 9 on Arrowrock Road, according to dispatch.
Deputies used a tow cable to pull the vehicle out and found the body, Rogers said.
“It did have a body inside, but it had been there more than a week,” he said.
Miller was one of 10 people who have died since 2009 after running off Arrowrock Road.
His body was found less than a mile east of where 2-year-old Riley Lutton went into Arrowrock Reservoir after he car he was riding in went off the road on May 23, 2014. The Mountain Home boy died three days later at a Boise hospital.
His father, Lawrence Lutton, pleaded guilty in April to vehicular manslaughter in 4th District Court in Idaho City. Judge Patrick Owen sentenced him to 240 hours of community service and four years of unsupervised probation. Owen granted Lutton a withheld judgment, which will allow Lutton to petition to have the case dismissed if he successfully completes his probation.
A Boise couple, Isaac and Jenny Hunter, died Valentine’s Day this year when their car plunged into Arrowrock Reservoir. Isaac Hunter, 34, lost control on a sharp curve near Milepost 14 and the car went down a 150-foot embankment into the water. Tests revealed he had a blood alcohol level nearly twice Idaho’s .08 percent when drivers are considered to be intoxicated.
