The final minutes of the ­15-year-old’s life played out in a series of videos, captured by the very people who killed her, according to a search warrant. They taunted Damaris A. Reyes Rivas, poked her with a knife and explained why they decided she would die.

The perpetrators, who included young members of MS-13, said on the recordings that the Gaithersburg teen was being executed in retaliation for the killing of a gang member, Christian Alexander Sosa Rivas, in Prince William County roughly a week earlier.

One of the juveniles was so brazen, a detective wrote in the search warrant, he wore a court-ordered GPS monitoring bracelet that pinpointed his location at the crime scene at the time of the teen’s slaying.

In the end, the chilling videos show Damaris lying supine on the ground in a Springfield park, suffering from multiple wounds and surrounded by dead leaves, according to the search warrant filed in Fairfax County Circuit Court.

The search warrant, which was made public Monday, offered fresh details in overlapping crimes tied to MS-13 that have left two young people dead, resulted in the arrest of 16 others and prompted fears about the renewal of the region’s largest and most violent gang. The search warrant was filed to get data from the juvenile suspect’s ankle bracelet.

Ten people ranging in ages from 15 to 21 have been arrested in connection with Damaris’s abduction and slaying. Her body was discovered in mid-February, a short distance from Lake Accotink Park, where she was tormented.

People familiar with the prosecution’s case said she was lured there under the pretext of smoking pot on or around Jan. 8, but after arriving, she was seized from a car by two alleged MS-13 members and walked into the woods.

The search warrant states that the videos of Damaris’s killing were discovered roughly two days after her death, as police in Prince William investigated the MS-13-related slaying of 21-year-old Sosa Rivas.

Damaris’s mother has said her daughter once dated Sosa Rivas of Fairfax. The two are not related. His body was discovered along the Potomac River in the Dumfries area in mid-January, and six have been charged in his killing.

The video clips were date-stamped Jan. 8, the day authorities believe Damaris was likely killed, and depict her interrogation and taunting by several males and at least one female, according to the search warrant.

At one point, detectives wrote in the search warrant, Damaris was jabbed with a large pointed stick.

People familiar with the prosecution’s case also said a female juvenile questioned Damaris about her relationship with Sosa Rivas before slashing her with a knife. A female juvenile who is charged with Damaris’s killing also had a relationship with Sosa Rivas, Prince William police have said.

The Washington Post generally does not name juveniles charged in crimes.

Robert Bermingham, director of court services for the Fairfax County Juvenile and Domestic Relations District Court, said he could not discuss the specifics of how the suspect with the GPS bracelet was allegedly able to participate in a brutal killing while under court supervision. He said that since the suspect is a juvenile, the details of his case are confidential.

“Preliminarily, there’s no indication we worked outside of policies and procedures,” Bermingham said.

He said the county has 12 to 15 juveniles under electronic supervision at any time. He said a probation officer monitors the bracelet for violations and also does face-to-face monitoring at least every other day.

NBC 4 reported that another search warrant states that Sosa Rivas may have been targeted by fellow MS-13 members because he was claiming to be the leader of a local clique. That search warrant says Damaris was one of the last people to see him alive but does not elaborate.

Court documents say that two women charged in Sosa Rivas’s killing used social media to lure him to the location where he was killed on or around New Year’s Eve.

Separately, Fairfax County police said Monday that it could take until March 17 to identify two sets of remains found buried in Fairfax County’s Holmes Run Park on Thursday. Police are exploring whether those apparent killings are also related to MS-13.
