Hidalgo County's sheriff says a man who was shot and killed by deputies on Tuesday night was speeding toward them in a truck and refused to stop. Sheriff Eddie Guerra spoke about the death of 53-year-old Enrique Martinez yesterday. Guerra said deputies were interviewing a domestic assault victim in Donna when Martinez drove toward them at high speed intending to hit them. Deputies fired at Martinez, striking him several times. The victim and one of the deputies were treated for injuries at a local hospital. The shooting is still under investigation.
