MILWAUKIE, Ore. (AP) — The search has been called off for the car that fatally struck a toddler on a Milwaukie residential street, police announced Monday night.

An unknown vehicle struck and killed a two-year-old boy, Jack Barrett, on the afternoon of July 2 when he opened the door of his grandparents’ house on Southeast Wichita Avenue and wandered into the street.

Police on Monday night said they had ended the search because they’ve determined the vehicle likely did not sustain much damage in the collision and the driver may not have been aware of what happened.

They also said the child’s autopsy indicates that speeding was not a factor in the crash, but said after feedback from the community, the city decided to reduce the speed limit on Wichita Avenue from 25 miles per hour to 20.

Police did not indicate whether they had more information about what factored into the crash, or whether they have identified any possible drivers.
