An Osteen man was charged with aggravated assault with a deadly weapon after he fired a gun at the driver of a vehicle who had witnessed a rear-end crash the shooter caused along State Road 415, deputies said.

Brock Allman, 22, also was charged with discharging a firearm from a vehicle in the 12:45 a.m. Sunday incident. He was released from the Volusia County Branch Jail after posting $5,500 bail, according to court records. Allman could not be reached.

Allman was seen by a motorist rear-ending a white SUV with his Dodge pickup as the vehicles were traveling north on S.R. 415 in Osteen, Volusia County sheriff's deputies said.

The witness, Fernando Bustamante, 23, watched as Allman made two U-turns and drove past the SUV that had stopped in a grassy median following the crash, according to an arrest report. Allman sped off and Bustamante pursued him in his vehicle after checking on the well-being of the driver in the SUV, deputies said.

As Bustamante got closer to the pickup to read its license plate, Allman fired at him, according to the Sheriff's Office.

Bustamante called deputies, who were able to track Allman to a house on Oak Drive because of tracks his pickup had left behind, the report showed.
