Jose Sifuentes had been a "person of interest" in the stabbing death of a 10-year-old Jasmen Gonzalez, on Tuesday he was arrested on a murder charge.
A family member is charged with murder in the death of a 10-year-old Oklahoma girl who was reported missing in Carrollton over the weekend.
The Dallas County medical examiner's office said Monday that Jasmen Gonzalez died of a stab wound to the chest. The girl was reported missing when her parents noticed she was no longer asleep in a bedroom in her aunt and uncle's apartment.
Jose Conception Sifuentes, 23, was charged in Gonzalez's death Tuesday. Sifuentes, the common-law husband of the Gonzalez's cousin, was a person of interest in the case before his arrest.
Gonzalez and her parents were visiting friends and family in Carrollton when she disappeared late Saturday night, police said.
Though crews searched overnight, the girl wasn't found until about 3:30 p.m. Sunday, when officers found her partially naked body lying facedown in the backyard of a home only a couple of blocks away from her uncle's apartment.
Police said they were confident Gonzalez was taken from the bedroom before she was killed, though they haven't revealed the location of a crime scene or a motive.
Investigators interviewed at least a dozen people in connection with the girl's disappearance and slaying, including Sifuentes.
Relatives told police the man disappeared from a family gathering Saturday night and returned after about a half an hour.
In an interview with detectives, Sifuentes' "statements were inconsistent, including information regarding him leaving the location for an undisclosed amount of time and his purpose for leaving," according to the search warrant.
Prior to his arrest Tuesday, Sifuentes was detained on an U.S. Immigration and Customs Enforcement hold.
His residence and black Lincoln Navigator were searched Monday. According to a search warrant, police found a knife and human blood in the vehicle.
An affidavit obtained by NBC 5 Monday morning confirmed there were signs that Gonzalez was sexually assaulted.
Officials said the district attorney's office will determine if additional or upgraded charges should be pursued in the case.
Sifuentes was moved from the Carrollton jail to the Dallas County Jail at 9:45 a.m. Tuesday.
