A senior Mexican police officer whose name appeared at the top of a hit list has been shot dead in a border city across from Texas.

City officials say gunmen sprayed Juan Antonio Roman Garcia’s car with bullets early Saturday outside his home in Ciudad Juarez. He was the city’s No. 2 police officer and at least the fourth high-ranking officer to be killed in Mexico in a week.

Roman Garcia’s name appeared at the top of a hit list found several months ago at a monument to slain police officers. Several people on it have been killed, and none of the perpetrators have been caught.
