I found this article on the New York Times website

This article about the Mexican cartels killing their mayors.

 

In mexico city on January 2, a team of hired killers set off for the home of 33-year-old Gisela Mota, who only hours before had been sworn in as the first female mayor of Temixco, a sleepy spa town an hour from Mexico City. Ms. Mota was still in her pajamas as the men approached her parents house. She was in the bedroom but most of her family was in the front room, looking over a newborn baby. As the family prepared a bottle for the baby , the assassins smashed the door open. to find out what the noise was, Ms. Mota came out of her bedroom and said firmly, “I am Gisela.” In front of her terrified family, the men beat Ms. Mota and shot her several times, killing her.

 

In 2009, American agents from the Drug Enforcement Administration got intelligence on where  Mr. Beltrán Leyvas is . The D.E.A. gave the address to Mexican marines — an elite American-trained force — who stormed in, killing Mr. Beltrán Leyva and four of his accomplices. A senior D.E.A. official told me they paid their informant a $5 million reward for the information that led to the takedown — taxpayer money spent to try and win the drug war.
