US Marshals and the Lake County Sheriff’s Office have arrested the third suspect in the murders of three teenagers in a rural Florida community last week.

The 16-year-old was arrested on outstanding warrants for carjacking with a firearm, aggravated assault, grand theft of a motor vehicle, fleeing or attempting to elude law enforcement, and tampering with an electronic monitoring device, the Marion County Sheriff’s Office said, which said that “additional charges are forthcoming.”

US Marshals and the Florida Sheriff’s Association had announced up to $5,000 in reward money for the suspects arrest; it’s not clear if anyone will claim the reward.

Deputies have already arrested a 17-year-old boy and a 12-year-old boy and charged them with first degree murder, Marion County Sheriff Billy Woods said. It’s unclear if any of the suspects have been charged as adults; until they are, CrimeOnline will not name them.

The 17-year-old and 12-year-old appeared in court on Saturday and were denied bond, WESH reported. They are also charged with robbery with a firearm.

Sixteen-year-olds Layla Silvernail and Camille Quarles and a 17-year-old boy were found last week in three separate locations of Marion County. Silvernail was critically wounded and later died at a hospital, the boy was found dead about a half mile away the next day, and Quarles was found shot to death in the trunk of Silvernail’s car on April 1, partially submerged in a pond about nine miles away.

According to the arrest affidavits for the 12-year-old and 17-year-old suspects, all six — the three suspects and the three victims — were involved in criminal activity on March 30 prior to the shootings before the suspects turned on the victims for an unknown reason and killed them, as CrimeOnline reported.

The affidavits say that the 16-year-old suspect first shot Silvernail and the 17-year-old boy while Silvernail was driving her car with the other in the back seat — except for Quarles, who was in the trunk smoking “by her own choice.” The 12-year-old and 17-year-old suspects both said they fired shots at the victims as well.

The group dumped the wounded Silvernail at the site of the shootings, then drove the car a little further and dumped the teen boy’s body in a ditch. They later dumped the car, with Quarles’ body, in the pond.
