Houston police have charged two men with capital murder in the death of a 12-year-old girl found strangled to death in a creek on Monday.

Franklin Jose Peña Ramos, 26, and Johan Jose Rangel Martinez, 21, are the two men seen on surveillance video with Jocelyn Nungaray on Sunday night, Houston Police Lt. Stephen Hope said.

As CrimeOnline reported, Nungaray is believed to have snuck out of her apartment Sunday night. She was reportedly on the phone with her 13-year-old boyfriend when she was overheard talking to two men.

Surveillance video from a 7-Eleven convenience store showed the two men approach the girl. Investigators said they used other video to track the two men from earlier in the evening, when they had dinner at a restaurant in Northborough and then left on foot. They met Nungaray near Kuykendahl Road and walked with her to a convenience store.

From the store, they walked to a bridge on West Rankin Road, where they killed the girl and left her body in the creek.

The two men were taken into custody Thursday morning at the Canfield Lakes apartments on Northborough Drive, where they shared an apartment.

Acting Houston Police Chief Larry Satterwhite said detectives worked around the clock to identify the men.

“Their hard work paid off. We were able to find video and trace the movements of our suspects and Jocelyn, all the way to the point of where she was murdered and left in a bayou,” Satterwhite said.

Satterwhite said the two men were initially identified as persons of interest and were detained for questioning Thursday morning while detectives executed a search at the apartment. There, he said, they found evidence connecting them with Nungaray’s murder.

Alexis Nungaray, the 12-year-old’s mother, told KTRK that she doesn’t believe her daughter knew the two men before Sunday night, but investigators have not said if they believe the girl and the two men were acquainted.

Hope said that communications and other digital information is among the “mountain of information” that investigators are pouring through.

Satterwhite said the US Department of Homeland Security is trying to determine the suspects’ immigration status.
