Two men were found dead in the wee hours of Friday inside a taxi in the San Juan neighborhood of Hato Rey, the Puerto Rico Police Department said.
The bodies bore multiple bullet wounds, the PRPD said in a short statement.
San Juan's acting police chief, Maj. William Ruiz, said investigators found no bullet holes in the abandoned taxi and that one of the vehicle's doors was left open.
The double-murder brings to 353 the number of killings reported in Puerto Rico so far this year, 99 fewer than at the same point in 2011, when the island experienced a record 1,000-plus homicides. EFE
