Detectives say the August 24 shooting that claimed the life of a teenager on I-4 was the end result of a neighborhood and online feud in the Plant City area.

On Monday, the Hillsborough County Sheriff Chad Chronister announced the arrests of three people.

The accused shooter – 20-year-old Jaris Dequan Youngblood was arrested in Tampa and charged with premeditated first degree murder with a firearm, shooting into a vehicle and tampering with evidence.

His brother – 22-year-old Jarkese Nicholas Youngblood – was arrested in Osceola and charged with being a principal to premeditated first degree murder and tampering with evidence.

The sheriff said Jarkese’s 19-year-old girlfriend was also in the car – along with her one-year-old daughter – when the fatal shots were fired. Sha’Quandra Clarnique Williams is charged with tampering with evidence. Detectives say she sold the car to a scrap yard.

Sheriff Chronister explained how the shooting of one person could easily have turned into a much more dangerous and deadly situation.

"Consider for a moment vehicles traveling at high speeds on I-4," he said. "Passenger vehicles, tractor-trailers, and heavy equipment haulers. If the victims' vehicle had lost control, we would be looking at an absolute catastrophe and most likely a devastating number of fatalities."

HCSO worked with the Plant City Police Department, the Tampa Police Department, the Florida Department of Law Enforcement and Florida Highway Patrol to determine if the August 24 shooting was connected in any way to several other recent shootings on I-4. Sheriff Chronister said investigators determined there was no link.
