Authorities continue to investigate a shooting Saturday that killed a popular coach and father of three off Dawson Forest Road in southern Dawson County.

Officials said Alan "Brandon" Weaver, 37, of Dawsonville died from injuries sustained in the shooting at a home on Whitney Place.

No arrests have been made in the case, though Dawson County Sheriff Billy Carlisle said his investigators know the shooter's identity.

"He's not in custody yet, but we know who he is. We are still interviewing all the witnesses right now to determine exactly what happened," he said Sunday.

An autopsy performed on Monday listed the cause of death as "gun shot to chest."

"Upon the completion of our investigation, our investigators, along with members of the District Attorney's office, will review the findings and determine the outcome of any charges, which may be brought," Carlisle said in a statement released by the sheriff's office.

Capt. Tony Wooten said Weaver was shot twice at close range with a handgun during a fight at the Whitney Place home.

Weaver's son had been at a birthday party at the home earlier that evening and had called his dad to say he wanted to go home.

Wooten said the child felt uncomfortable about something going on at the party.

Weaver reportedly picked the child up and took him home, but later that night returned to the home with another man, who has not been identified, to confront the people living there.

The two engaged in words that led to a fight with two men at the home.

"A 9-1-1 call was made...and shortly after, the shooting occurred," Wooten said.

Weaver was hit twice. He died on the scene.

"There's a lot of leads that still need to be followed," Wooten said.

While the investigation is ongoing, Wooten did say that alcohol was a factor.

"That makes our jobs more difficult in that we have to go back and re-interview the people from that night after the fact," he said.

"One of the biggest things for investigators is to try to determine why [Weaver] returned to the residence."

Carlisle said the shooting is a "tragedy to our community."

"We ask that you respect the privacy of both families involved, as this is a difficult time for everyone. We appreciate your concern and patience as we continue a thorough investigation," he said.

Weaver is survived by his wife Heather Weaver, three young sons, numerous family members and friends throughout many communities.

A well-known coach with Dawson County Parks and Recreation, parks director Lisa Henson called him a great father, coach and friend.

"He was a big kid himself and always made sure the kids he coached were having fun while learning and growing as young athletes," she said. "He raised the bar for coaching youth sports and we will miss him. Our prayers are with his loving [family]. This is a huge loss for our park and rec family and community."

The Mitchell, S.D. community where he attended college is also mourning his death, according to friends who were shocked to hear the news.

"Brandon played football here at Dakota Wesleyan University and Heather worked with me in the...admissions office. Both were loved by everyone they met and were missed when they moved back home," said friend Brad Zomer.

"Brandon was a great man and was not afraid to share his faith in Jesus Christ. And while we mourn the loss of a great friend, we can be assured that heaven just got a little more lively."

Tammie Pearson, also from Mitchell, said he will be missed tremendously.

"He was full of life, passion and love for his community, and in true since of the word, a southern gentleman," she said. "He was one of the good guys."
