New search warrants reveal the men accused of killing 12-year-old Jocelyn Nungaray are possibly members of the Venezuelan gang Tren de Aragua.
Franklin Pena, 26, and Johan Martinez-Rangel, 22, were indicted last month on capital murder charges in connection with Nungaray's murder.
Documents say Pena and Rangel kidnapped the 12-year-old and caused her death by applying pressure to her neck. The two are also accused of sexually assaulting her before leaving her body under a bridge.
The new search warrants regarding the alleged gang involvement were filed in the District Court of Harris County and obtained by FOX 26 Houston.

The men's alleged association with the gang, also known as TdA, was discovered after searching their social media accounts.
The TikTok account believed to be linked to Rangel had used ninja, crossed swords and classical building emojis, which are known to be associated with the gang. TikTok did not immediately respond to a Fox News Digital request for comment regarding the new search warrants.
Investigators also observed a video of Rangel "wearing Jordans and Gucci," brands also connected with the gang.
Pena's TikTok account had photos showing tattoos known to be associated with the TdA gang, which included one star on each shoulder and a rose tattoo on his hand. He was observed on video wearing Air Jordan brand and Chicago Bulls brand clothing, the search warrant says.
"I believe that Johan Jose Martinez Rangel and Franklin Jose Pena Ramos utilized multiple social media applications and accounts to communicate with gang members about gang activities," one of the investigators wrote in a search warrant.
The search warrant requests further data from the suspects' phones and social media accounts, in search of more evidence to tie the men to their alleged offense of capital murder.
