MARION COUNTY, Fla. (WFLA) — Two juveniles are facing murder charges in the shooting deaths of three teenagers in Florida last week.

Marion County Sheriff Billy Woods announced Friday the arrests of a 12-year-old boy (who WFLA will not name due to their age) and 17-year-old Robert Robinson, for their alleged ties to the three murders. Woods said one other suspect, 16-year-old Tahj Brewton, remains at large.

A combined $10,000 reward was offered for information leading to Brewton’s arrest. Authorities said the teen, who is wanted for several other felony offenses including carjacking with a firearm and aggravated assault, should be considered armed and dangerous.

The suspects and victims were part of a gang and would commit robberies together, Woods said, but things took dark a turn.

“Basically, in simple terms, there’s no honor among thieves,” Woods said, “And at some point, these three individuals turned on our three victims and murdered them.”

Here is what we know about the case so far:

March 30: Marion County deputies were called to the area of Forest Lakes Park on S.E. 183rd Avenue Road. Layla Silvernail, 16, was found laying beside the road with a gunshot wound. She later died. Silvernail’s car was spotted in the area at around 10:40 p.m.

March 31: An unidentified 17-year-old boy was found laying along the road at S.E. 94th Street and S.E. 188th Court. Deputies said he died from a gunshot wound.

April 1: A car was found partially submerged near Malauka Loop and Malauka Loop Trace. A dive team discovered the body of a 16-year-old girl inside the trunk. The teen, identified as Camille Quarles, also died from a gunshot wound. Silvernail’s car was spotted in the area at around 1 p.m.

On Friday, Sheriff Woods said evidence collected from her phone indicated Quarles traveled to the area “of her own free will.”

The sheriff’s office released a photo of Silvernail’s 2015 Chevy Cruz, asking the public for information on its whereabouts between 10:48 p.m. on March 30 and 1 p.m. on April 1.

Woods said all three suspects were inside the vehicle when a witness reported hearing gunshots and watching the car bump into a dumpster. Although they fled the scene of each crime, they reportedly left a lot of evidence behind, according to Woods.

The State Attorney’s Office is reviewing the case to determine if any of the suspects will be charged as adults.
