For the first time, someone called police, claiming to be the sniper responsible for 20 highway shootings, authorities said Friday.
Chief Sheriff's Deputy Steve Martin said that the call is being taking seriously and that the task force investigating the shootings at cars, school buses and homes is trying to confirm whether the caller was the sniper.
Martin would not give details about what was said in the call, when it was made, whether it had been traced or whether the caller was a man or woman.
One person has been killed in the shootings since May along or near Interstate 270. No one else has been struck. The most recent shooting was Jan. 22.
