The six murders recorded last weekend in Puerto Rico brought to 406 the number of violent deaths on the island so far in 2012, 93 fewer than in the same period last year, police said Monday.

The list of fatalities includes the death of a 20-year-old security guard in San Juan's Carolina neighborhood, slain on Saturday while on duty patrolling the area.

A 49-year-old man was found dead this weekend inside a barber shop in the interior town of Barranquitas. Police have as yet found no clues that might lead to the perpetrator.

Other murders were reported in the districts of Arroyo, Guayama, Dorado and Guaynabo.

Despite these latest slayings, the number of homicides so far in 2012 is less than in the same period of 2011, a year that ended with 1,136 violent deaths, some 15 percent more than in 2010 and the highest number of murders since records began to be kept in 1940. EFE
