D.C. police are looking for two men suspected in the killing of a Northwest Washington man who was found fatally stabbed in Rock Creek Park last month, officials said.

Authorities issued an arrest warrant on a charge of second-degree murder while armed for 40-year-old Angel Dilmar Monge, who police believe stabbed Matias Molina. Molina, 49, was found with stab wounds along a creek bed near Beach Drive and Joyce Road NW on Sept. 2.

The two suspects were co-workers at a local restaurant and investigators believe Molina was fatally stabbed during an argument, said Acting D.C. police Capt. Robert Alder, the commander of the homicide unit. Alder declined to say why the men argued.

Police are also looking for an alleged accomplice, whom they identified as Jose Santos Cantarero. He is wanted on a charge of accessory after the fact, officials said.

Investigators believe Molina was killed and his body dumped in the park.

“We did conclude that the homicide did not occur in the park,” Alder said. He declined to say where police think Molina was killed or what weapon was used.

Officials said Monge also uses an alias of Alex Avalos and he is described as 5’6” tall and weighing about 180 pounds, with black hair and brown eyes. He also has a black scorpion tattoo on his left forearm, police said.

Police described Cantarero as 5’10” tall, weighing 180 pounds, with black hair and brown eyes.

“We do believe they may have fled the area,” Alder said, but police warn that both men should be considered armed and dangerous.
