Terry Brian Riveria identified, charged with Capital Murder for 12-year-old's death

She is charged with hindering apprehension/prosecution, which is a felony.

Rivera is wanted for the murder of 12-year-old Carlos Fernandez while he was sleeping in his bed. 

Family members spoke with FOX 26 Sunday afternoon about the arrest at Vasquez Funeral Home, where visitation services were underway for Fernandez. 

"We know them," said Delfino Gonzalez, Carlos' uncle. "We expected it, but we have to let the investigators do their job. I don't want anyone else to get hurt. I don't want any kids to get hurt. None of that. We need to get this guy off the streets." 

According to Sheriff Ed Gonzalez, Rivera was in a previous relationship with the 12-year-old's mother and had two children with her. They were together for six years and were separated on and off for two years.

Harris County deputies were confirmed to have been called to the home before the shooting. Fernandez's mother says Rivera had dropped the kids off around 10 p.m. and was being loud and confrontational.

Rivera is still on the run and should be considered armed and dangerous. 

"It's tough. It definitely doesn't get easy. We're just trying to deal with it day by day...and trying to be there for my sister," Gonzalez added. Funeral services conclude Monday afternoon.
