Justin Alan Foster, 30, of Loganville, faces 14 charges including aggravated assault with the intent to murder after he was arrested Tuesday afternoon for allegedly assaulting Dawson County Sheriff's Office Sgt. Randy Harkness.

An email from Sheriff Jeff Johnson states that warrants obtained for Foster charge him with two counts of battery, three counts of hijacking a motor vehicle, aggravated assault, aggravated battery, aggravated assault with the intent to rob, aggravated assault against a peace officer, aggravated battery against a peace officer, obstruction, attempted removal of a weapon from a public official, robbery by force and aggravated assault with intent to murder.

Authorities are currently investigating the incident that allegedly occurred around 2:40 p.m. Dec. 5.  

According to Johnson, Harkness had dropped Foster off at the Chevron on Ga. 400 near the McDonald's following a courtesy ride, and was in the process of giving Foster money when Foster allegedly began to assault him.

During the assault, a female bystander shot Foster at least once, Johnson said. Foster then fled across the road to the McDonald’s parking lot where he assaulted an elderly woman.

Additional “good Samaritans” at the McDonald’s detained Foster until officers arrived, Johnson said.

Johnson said earlier this week that a female bystander who shot Foster as he was assaulting Harkness likely saved the officer's life, as well as other potential victims.

 "I truly believe through her actions he's here today," Johnson said Tuesday.

Officials have not released the identity of the bystander. It is not likely she will face any charges.

Harkness, 52, has worked for the sheriff’s office for nearly 24 years. He received serious injuries to his head and neck and was transported to an area hospital. He has since been released.

The elderly woman was also struck in the head and transported. She has also been released.

The suspect was also transported to an area hospital to be treated for a gunshot wound. He is still in the hospital under guard, Johnson said.

All are expected to recover from their injuries. 

The identities of the elderly woman, as well as the identities of the good Samaritans, have not been released at this time.
