Rigoberto Rouqu Portela, a 50-year-old man, was shot on the night of September 26, 2008, in the Langley Park area near Hyattsville, Maryland. Around 9:50 p.m., patrol officers were dispatched to the 8100 block of 15th Avenue for reports of a shooting. When they arrived, they found Portela suffering from gunshot wounds, and despite the emergency response, he later died from his injuries.
In the hours and days that followed, detectives worked the case quickly and focused on identifying who had been with Portela and what had led to the gunfire. Investigators developed Efrain Antonio Osorio as a suspect during the course of the investigation, and a warrant was obtained the very next day, September 27, 2008. With the warrant in place, police were no longer looking for answers in the abstract—they were looking for a specific man they believed was responsible for Portela’s death.
But the suspect was gone. Authorities said Osorio fled Maryland and, for years, stayed out of reach, effectively turning a single late-September homicide into a long, grinding manhunt that stretched well beyond Prince George’s County. The case lingered in that frustrating space where a name exists but a body cannot be put in handcuffs, and the passage of time threatens to dull leads, scatter witnesses, and bury the truth under everyday life.
That changed in 2013. Detectives learned Osorio was living in Texas under an assumed identity, and Prince George’s County officers coordinated with the Lone Star Fugitive Task Force. On November 7, 2013, Osorio was located in Georgetown, Texas, and taken into custody without incident. He was held in Texas while awaiting extradition back to Maryland, ending a five-year stretch in which police said he had managed to elude capture.
Later reporting about Osorio indicates the case ultimately resulted in a conviction: ICE described Efrain Antonio Osorio-Osorio as having been convicted of second-degree murder and use of a handgun during the commission of a crime in Upper Marlboro, Maryland, and sentenced to 30 years for the murder conviction plus 20 years for the handgun offense.
