A teenager and two 21-year-olds died Saturday in a single-vehicle crash along a rural road in Damascus.

The Clackamas County Sheriff's Office is investigating. Speed may have been a factor, according to authorities.

The victims are: Curtis Sowell, 16, of Oregon City; Drew Noble, 21, of Cove in eastern Oregon; and Brenna Collacchi, 21, of Clackamas. Collacchi attended Clackamas High School in 2014 and was named prom queen. According to her Facebook page, she and Noble were dating.

The crash occurred in the 13500 block of Southeast Wiese Road, about a half-mile north of Oregon 212.

The crash was reported at about 11 o'clock -- but it's not immediately clear whether that was in the morning or evening. A sheriff's spokesman didn't specify and didn't immediately respond to a request for clarification.
