A woman died today while bicycling in southeast Portland.

The collision with an auto user happened around 3:00 pm at SE 112th and Mount Scott Boulevard. This location is near the entrance of Lincoln Memorial Park, a popular area for riding.

The police have not yet released details of the collision.

This is the fourth fatal bicycle collision and the 27th traffic fatality in Portland so far this year.

This is the second person to die while bicycling this week. On Saturday a Lydia Johnson was killed at SE Flavel and 82nd.

UPDATE: Here’s the latest from the police:

The bicycle rider killed on Friday afternoon has been identified as 49-year-old Karla Kalene DeBaillie of Happy Valley, Oregon.

The other driver involved in the crash was identified as 64-year-old Mary Elizabeth Dieter of Washougal, Washington. Dieter was driving a blue 1997 Dodge Ram pick-up truck. Dieter cooperated with investigators and did not display any signs of impairment or distracted driving.

Based on witness statements and evidence collected at the scene, investigators believe that DeBaillie was riding at a speed of 30-35 miles per hour down Mount Scott Boulevard (northbound) and turned left (westbound) at the interchange at 112th Avenue.

Dieter was driving eastbound on Mount Scott Boulevard and was moving to turn left onto 112th Avenue as westbound traffic stopped to allow her to turn. As Dieter crossed over the westbound lane of Mount Scott Boulevard, DeBaillie crashed into the passenger side of the pick-up truck.

The investigation is continuing and once complete it will be given to the Multnomah County District Attorney’s Office for review.
