(CNN) -- Funeral services were held Sunday in the college town of Athens, Georgia, for Senior Police Officer Elmer "Buddy" Christian, shot point-blank Tuesday during a carjacking investigation that spiraled into a SWAT-led manhunt and a hostage standoff.
An honor guard lined the streets while hundreds of mourners watched as Christian's body was escorted to a local funeral home, WSB-TV reported.
Christian was killed Tuesday during a carjacking investigation that led to a shootout between Athens-Clarke County police officers and suspect Jamie Donnel Hood.
The fire exchange critically wounded Senior Police Officer Tony Howard as both men tried to make an arrest.
Hood -- now in custody -- managed to escape but surrendered Friday in front of live TV cameras, releasing eight people held hostage in an apartment.
After a massive, four-day manhunt, SWAT officers descended on Hood, negotiating a hostage release. At one point, authorities used the media to get a message to Hood.
"I want to commit to you, if you come out without a weapon, you will not be harmed," Vernon Keenan of the Georgia Bureau of Investigation said in a televised address.
Hood had asked negotiators to bring his mother to the scene, said John Bankhead, a GBI spokesman.
During negotiations, Hood insisted that he be arrested on live television because he feared authorities would kill him, CNN affiliate WGCL reported.
The incident began Tuesday afternoon on the east side of the city when a vehicle was carjacked, said Hilda Sorrow, a police spokeswoman. Hood, who was believed to be involved, was later seen as a passenger in a red SUV, she said.
When Howard stopped the SUV, the man believed to be Hood got out and began shooting, police said. As the gunman ran off, he came across Christian's patrol car and fired into the vehicle, Sorrow said.
The gunman eventually reached a highway and carjacked a Chevrolet Prizm, police said. It was later found abandoned, Sorrow said.
Hood was being held without bond Saturday in the Hall County Detention Center, Captain Eric Pozen of the Clarke County Sheriff's Office said.
