The legislator-elect of the Institutional Revolutionary Party, or PRI, for the state of Sonora, Eduardo Castro Luque, was shot and killed in front of his home in the municipality of Ciudad Obregon, local Mexican press said Saturday.

The attack occurred around 8:55 local time (0155 GMT) on Friday, just as Castro Luque arrived home in an SUV and, a few steps from his front door, an individual on a motorcycle shot him several times with the bullets hitting his vital organs.

The local lawmaker, elected by Cajeme's 17th District, lost his life a few hours later in the emergency room of the Mexican Social Security Institute, the Sonora state Attorney General's Office said.

The news was also confirmed by the administrator of the legislator's personal Twitter account, who before dawn tweeted: "The Social Network Team of Lawmaker-elect Eduardo Castro Luque regrets to inform of his lamentable death. Our prayers with his family, his wife Rossana and his son Eduardito. Rest in Peace."

Castro Luque was a businessman with a wide-ranging career. He was president of the Chamber of Commerce, Services and Tourism, owner of an advertising agency, director of Expo Obregon, as well as marketing manager of Ciudad Obregon's Club Yaquis.

He was one of 14 legislators-elect for the PRI that on Sunday were going to make a protest in the name of the 60th legislature.

Northern Mexico is the scene of endless bloody wars between drug cartels vying for control of the local market and of drug-trafficking routes to the United States. EFE
