Louisiana police have tracked down a Texas man accused of assaulting and murdering his 11-year-old neighbor, Maria Gonzalez.

Authorities in Shreveport, Louisiana, took Juan Carlos Garcia Rodriguez, 18, into custody Saturday after Harris County, Texas, officials charged him with capital murder in connection with the girl's August 12 death.

Maria was home alone on August 12 when she texted her father, Carmelo Gonzalez, that morning saying that someone was knocking on their apartment door.

"I told her, ‘Don’t open the door, because I am arriving at work,’ and she responded, ‘I am in my bed,’" Gonzalez told FOX 26 Houston.

While investigating the crime scene, detectives found a single key that could not be used to open any of the doors in the apartment where Maria was found. The key did, however, open another door in the apartment complex. Investigators then interviewed Garcia Rodriguez.

Authorities told FOX 26 that many undocumented immigrants live in the city just east of Houston, so some residents are hesitant to speak with police, but their main priority is to find the suspect in Maria's murder. (Google Maps)

The suspect was last seen in the apartment complex Monday around 4 p.m. and had not been seen since until police tracked him down in Louisiana on Saturday.
