JACKSONVILLE, Fla. -- A man is accused of shooting and killing the driver of a moving vehicle after experiencing an adverse reaction to the street drug, "Loveboat," according to the Jacksonville Sheriff's Office.

Tyrell Brown, 32, allegedly woke up and shot 25-year-old Steven Grady while the vehicle he was inside was traveling down Interstate 95 North on Sunday morning. Grady was the driver of the vehicle and lost control following the shooting.

A passenger in the back seat gained control of the vehicle before it crashed near Union Street. the incident occurred at about 3:15 a.m. Sunday.

Police say this was not a random act of violence done by a stranger.

When police arrived at the scene after the passenger in the back seat got control of the vehicle, Brown violently resisted police and was transported to UF Health for his safety. He is being charged with murder.

The JSO lieutenant who spoke with media believes those in the vehicle may have used drugs prior to the shooting.

That drug, as listed in the arrest report, is known as "Loveboat," which is a cigarette dipped in formaldehyde, or embalming fluid. It's unclear in this case if the cigarette was a general one or filled with marijuana, but the people in the vehicle did admit to smoking marijuana at some point that night.

According to Gizmodo, "Loveboat" has numerous varieties, some including liquid PCP.
