Authorities investigating a body found at an Oklahoma City apartment complex say it may be than of a 17-year-old girl who disappeared after a July 4 party.

Eduardo Bonilla-Lopez, 18, was arrested last month and charged with the kidnapping and murder of Haylie Gonzalez after he allegedly showed her bleeding from a gunshot wound to the head while FaceTiming with a friend.

Bonilla-Lopez reportedly told investigators that after the video chat he drove Gonzalez to another location where he had someone else dispose of her body, as CrimeOnline previously reported.

Oklahoma City Police were called to the apartment complex at about 8 a.m. Monday and were on the scene for several hours, News9 reported. Yvonne Turner, Gonzalez’s mother, told the station that detectives called her and said they “believe that we found her.”

Gonzalez was last seen at the July 4 party at the home of Bonilla-Lopez. Investigators learned that Gonzalez had called a friend that night asking for a ride and that she had sounded scared.

Bonilla-Lopez allegedly asked his friend for help disposing of Gonzalez’s body in the FaceTime call, but the friend refused, telling Bonilla-Lopez to take the girl to a hospital. But Bonilla-Lopez rejected that suggestion, saying he did not want to go to prison.

Oklahoma City Police arrested Bonilla-Lopez on July 12. His father and sister have also been arrested and charged with helping him conceal the crime.

Police said they were waiting for the medical examiner to positively identify the body and determine cause of death.

Gonzalez’s family said that if it is the 17-year-old, they plan to take her back to Texas, where she’s from, for burial.
