Iowa Hill Shootout Ends Multi-County Manhunt as Fires Spread

At approximately 4:00 AM on Monday, tactical officers found 44-year-old Derek Spencer in the forest near Iowa Hill. He was positioned behind a dirt berm and opened fire on the approaching officers. Law enforcement returned fire, fatally wounding Spencer.

The confrontation followed a weekend crime spree that crossed several Sacramento-region counties. On Saturday, Placer County sheriff’s deputies received reports that Spencer had brandished a firearm. He later entered adjacent El Dorado County, where authorities said he stole a vehicle, obtained several firearms, and fired shots at a moving passenger car.

Iowa Hill is an unincorporated, isolated community approximately 60 miles northeast of Sacramento. Located on a ridge about 2,900 feet above sea level, the historic Placer County territory has steep canyons cut by the North Fork of the American River, dense pine timber, and narrow, winding dirt roads. The terrain made access difficult for emergency vehicles and law enforcement tactical units.

Before the final search, Spencer had three recent encounters with the justice system. Sacramento County sheriff’s deputies arrested him on September 3 on suspicion of felony vandalism, assault with a deadly weapon, and resisting arrest. He remained in custody for eight days and was released on September 11.

On September 13, Folsom police officers arrested Spencer on suspicion of burglary. Under California’s pretrial release protocols, which evaluate non-violent suspects for release to manage jail capacities and ensure due process, he was released that same day on his own recognizance.

The following week, on Tuesday, Sacramento County sheriff’s deputies arrested Spencer again, this time on suspicion of vehicle theft. He was released the next day, Wednesday, after posting bond.

By Sunday, automated tracking and investigative leads had placed Spencer in the remote Iowa Hill wilderness. When a Placer County sheriff’s patrol unit spotted him, Spencer rammed the deputy’s vehicle and ran into the dense forest. During the initial pursuit, he fired rounds at ground deputies and at a law enforcement helicopter providing aerial assistance.

As tactical teams formed a perimeter and told residents to lock their doors, deputies searched a nearby residence where Spencer was known to have associations. They found a deceased woman inside. Investigators concluded that Spencer had shot and killed her before fleeing farther into the wilderness.

The overnight search brought in the El Dorado County Sheriff’s Office, the Nevada County Sheriff’s Office, the Roseville and Rocklin police departments, and the California Highway Patrol. Specialized air units, canine teams, and ground officers moved through the steep, pitch-black mountain terrain, using aerial drones and forward-looking infrared (FLIR) thermal imaging to follow Spencer through the brush.

During the final hours of the manhunt, Spencer deliberately ignited wildland fires in the dry underbrush to hinder the pursuit. The active gunfire and immediate threat to life forced crews from the California Department of Forestry and Fire Protection (Cal Fire) to stage at a safe distance, leaving them unable to reach the growing flames.

The shootout brought a violent end to the multi-county operation and allowed firefighters to enter the area. After Spencer was neutralized, Cal Fire crews moved in and contained fires that had spread across approximately five acres of timberland. Firefighters remained on scene Monday to monitor the extinguished burn area for potential flare-ups, while the localized wildfire threat had required rural residents to shelter in place and delayed emergency fire containment efforts.

The Placer County Sheriff’s Office is leading the active investigation into the shootout and the homicide of the woman found in the Iowa Hill residence.
