High school student killed by school bus in Western Pa.

MCKEESPORT, Pa. -- County homicide detectives are investigating after a 15-year-old high school student was fatally struck by a school bus while crossing a busy street outside of a crosswalk.

Parents say they've worked to no avail to get a crossing guard near where Deonte Cobbs was struck Thursday afternoon near McKeesport Area High School and Founders Hall Middle School. Both are on the school district campus in McKeesport, about 10 miles southeast of Pittsburgh.

A 14-year-old girl was killed by a dump truck in March 2014 while crossing the street near the same intersection.

McKeesport police didn't immediately return a call Friday, and haven't identified the school bus driver nor said whether a citation or charges may be filed.

Allegheny County detectives were called in because of the boy's death.
