SUMMERVILLE, S.C. (WCBD) – Authorities in Summerville arrested and charged four people in connection with a deadly shooting and body found inside a burned vehicle last month.

An investigation into the death of 20-year-old Omarion Brown determined the man was murdered within the Summerville Police Department’s jurisdiction.

Summerville PD’s Criminal Investigations Division began investigating Brown’s murder on April 19, and arrest warrants were secured on four people identified as suspects in the case.

Brandon Steplight, 19, Dominique Dawson, Jr., 18, Tyshawn Mashack, 23, and Zyon Vaughn, 17, who was charged as an adult, were arrested on Tuesday morning. Their charges are as follows:

• Brandon Steplight was charged with Accessory After the Fact to Felony Murder.
• Dominique Dawson, Jr. was charged with Murder and Possession of a Firearm During the Commission of a Violent Crime.
• Tyshawn Mashack was charged with Murder and Possession of a Firearm During the Commission of a Violent Crime.
• Zyon Vaughn was charged with Murder and Possession of a Firearm During the Commission of a Violent Crime.

Deputies with the Charleston County Sheriff’s Office (CCSO) initially responded to a call regarding a vehicle fire on Koester Road on April 13. Once flames were extinguished, a body was found inside.

The Charleston County Coroner’s Office identified the victim as 20-year-old Omarion Brown, and his death was deemed a homicide. Deputies later arrested Brandon Steplight, 19, on a charge of arson in the first degree and destruction or removal of human remains.

An autopsy found two bullets still in Brown’s chest area and no smoke damage in the lungs, indicating that Brown was dead before he was set on fire.

Video evidence collected by CCSO initially connected Steplight with the burned vehicle.
