Gunmen ambushed a police major in front of his home in the northern Mexican city of Chihuahua, killing the officer and wounding a passerby, authorities said.
Jose Luis del Bosque was assigned to the counternarcotics unit of the Chihuahua state Attorney General’s Office, a spokesman for the office, Carlos Gonzalez, told the media.
The attackers fled the scene in two vehicles after Monday’s shooting.
A woman struck by a stray bullet was listed in stable condition at a clinic in the city, municipal officials said.
Media accounts say the Juarez drug cartel put up a sign Sunday on a main street in Chihuahua city – the state capital – vowing to kill one state police officer per day in reprisal for authorities’ alleged collusion with the rival Sinaloa cartel.
Chihuahua, which ranks 11th in population among Mexico’s 32 jurisdictions, accounted for almost a third of the more than 15,000 drug-related killings reported nationwide last year.
The state’s largest city, Ciudad Juarez, suffered upwards of 3,100 homicides in 2010 and is already nearing the 500-murder mark less than three months into 2011.
Located just across the border from El Paso, Texas, Juarez is by some measures the world’s most-dangerous city.
