KENNEWICK, Wash. -

Police in Kennewick, Wash., say it appears that an 8-month-old Kennewick boy died accidentally while sitting in his stroller.

The Tri-City Herald reports that police say Benjamin Momotok's mother put him in the stroller Saturday for 30 minutes to an hour and when she checked on the boy he wasn't breathing.

Police say he apparently slid down in the stroller and a crossbar blocked his airway.

Benton County Coroner John Hansens says autopsy results are pending. The coroner says he saw no signs of abuse.
