KANSAS CITY, Mo. (AP) — A man charged with 10 shootings on Kansas City-area highways says he can prove he’s innocent.

The Kansas City Star reports Mohammed Whitaker is basing the claim largely on one piece of evidence that tracked which cellphone towers handled calls from his phone on April 2, the day of the sixth shooting.

He says if the time on the report — 5:30 p.m. — is correct, he could not be responsible for a shooting that day near Grandview. The records place his phone about nine miles from the shooting site just six minutes before it happened. He says he could not have covered that distance during rush hour on his way home from Overland Park, Kansas.

Police and prosecutors declined to discuss the April 2 incident or Whitaker’s claims.
