The remains found in Virginia pond on Sunday are believed to be those of a 17-year-old girl who went missing earlier in the day after she and her friends left a mosque, police said.
Fairfax County police charged 22-year-old Darwin Martinez Torres, of Sterling, with murder in connection with the case.
The teenage girl, whose identity has not been released, was walking outside with a group of friends when she got into a dispute with a man in a car at around 4 a.m. Sunday, according to police. The man allegedly got out of the car and assaulted the girl.
She then got separated from her friends, who ran away from the scene and called the police once they realized she was missing, according to authorities.
Police arrested Torres after a search and later obtained a murder warrant charging him with her death. It was not immediately clear if he had obtained an attorney.
"The Office of The Chief Medical Examiner will conduct an autopsy to confirm the identity of the remains and determine the exact cause and manner of death; however, detectives do believe the remains are those of our missing teen," the Fairfax County Police Department said in a statement Sunday.
The remains were found in a pond at around 3 p.m. Sunday in Sterling, located about two hours north of Richmond.
Police said they looked into whether the murder was a hate crime but said they found no indication "that this was a bias incident."
The teens had been participating in an overnight activity at a local religious center, according to police, but they did not identify the center by name.
The All Dulles Area Muslim Society in Sterling said officials there called the police after the girl's friends ran in for help. It was not clear if the teens were affiliated with that particular religious center.
"We are devastated and heartbroken as our community undergoes and processes this traumatic event," the center said in a statement. "It is a time for us to come together to pray and care for our youth."
Virgina Attorney General Mark Herring urged the people to show "love and support" for All Dulles Area Muslim Society and the Muslim coummunity.
