LA PLATA COUNTY, Colo. — A 16-year-old is in custody after he allegedly attacked and killed a woman and a 12-year-old boy at a home southeast of Durango Thursday morning, officials said.

According to La Plata County officials, officers initially learned of the incident when a driver reported that he had been involved in a single-vehicle accident around 7 a.m. Based on the preliminary investigation, officials believe the suspect, who fled on foot from a home on Snowy Peaks Way in suburban Southwest Horizon Ranch, caused the other driver’s accident.

While details are still being investigated, Ted Holteen of La Plata County said investigators currently believe the motorist involved in the crash directed a deputy to the home they saw the suspect fleeing from, which is nearby .

Inside the home, sheriff’s office deputies found a 12-year-old boy and a 12-year-old woman – who investigators believe is the suspect’s mother – with serious injuries. The boy appeared to have stab wounds and the woman was injured by an attacker who used a blunt object, La Plata County authorities said.

The boy died from his injuries. The woman was taken to CommonSpirit Mercy Hospital in Durango.

Their names have not been published.

As they searched for the suspect, authorities issued a protective order for a four-mile radius of U.S. Highway 160 and Colorado Highway 172, known as Elmore’s Corner.

About six miles down the road from the crime scene, a resident spotted the suspect and called 911. The suspect was arrested on Escalante Drive near the Rocket Pointe apartments after officers used a stun gun, La Plata County authorities said.
