CRIME, teenager found dead on tracks [FP]

The police say the train hit Brandon Washington. The medical examiner's initial findings say he was killed by a head blow, not caused by a train. See Forest Park Review (Seth Stern).

Keating said there is no conclusive evidence regarding how Washington got onto the tracks, but that police do not suspect foul play at this point.

"Investigators spoke to the family to see if he had any problems, and as far as we can tell he was just trying to get home," he said.

What does "do not suspect foul play" mean?
