Drug hit men execute policeman and his 4 year old daughter; wife, 2 other kids hurt

The events occurred yesterday in the city of Chihuahua, an industrial and commercial center of 825,000 in northern Mexico.

The officer, 32 year old Jean Calet Aguirre, had served seven years as a state police officer. It was his day off, and he was driving down a busy street with his family. Gunmen pulled up in a vehicle and cut him off. Police say that traffic was heavy and the area was congested, so the officer couldn't escape. Aguirre and his 4 year old daughter were killed at the scene. His wife and two other children remain in serious condition.

More than 10,000 people died from drug violence in Chihuahua in 2010, where two cartels -- Los Zetas and Cartel del Golfo -- are engaged in a deadly turf war. The state borders New Mexico and Texas on the north.
