Donna Betts is arrested on 18 counts of aggravated assault.

SARASOTA COUNTY — A man told a Sarasota County 911 operator that Donna Betts, the wife of Allman Brothers Band founding member Dickey Betts, stood on her dock Monday evening looking through the scope of a rifle, which was pointed toward 100 teens and coaches with the Sarasota Crew team.

Donna Betts, 62, was arrested at her Osprey home this morning and charged with 18 counts of aggravated assault with a firearm.

According to the Sarasota County Sheriff’s Office, Betts appeared on the dock behind her home in the 300 block of Palmetto Avenue about 5:30 p.m. Monday and pointed a rifle at members of Sarasota Crew, who were in boats and on a nearby dock preparing for rowing practice. Betts allegedly threatened to shoot different crew members and coaches as she pointed the rifle at them, and made statements that if they came on her property they would be shot.

Much of the incident was captured in a cellphone video, which corroborates the claims, according to deputies. Deputies recovered the weapon, which Betts allegedly threw into the water.

According to the Sheriff's Office, Betts then called 911 at 5:43 p.m., identified herself and said that the rowers have destroyed her life.

Betts lives on a property adjacent to the crew team’s practice facility at Bay Preserve at Osprey. The man who called 911 said this wasn’t the first run-in they’ve had with Betts, and there was a restraining order against the woman.

“She’s on her dock looking through the scope and aiming at the kids right now,” the man told a 911 dispatcher who calmly told the man help was on its way. “We’ve got hundreds of kids here, she’s pointing the gun at one of my coaches generally right by me right now.”

The man can be heard yelling to teenagers and staff to “get the hell away” until the incident had been resolved.

The man said Betts, who was allegedly standing at the end of her dock, then threw the rifle about 10 feet off the northwest corner of the dock into the Intracoastal Waterway, and said he believed she was drinking.

“She’s walking back into her house now,” the 911 caller told the dispatcher. “She said she is going to get a loaded gun.”

The 911 caller said no one was “physically” harmed during the incident and the rowers were moved away from the scene to keep them from witnessing the confrontation.

The caller said there have been previous arguments with Betts but incorrectly stated that it was the first time the Betts displayed a gun.

On Dec. 16, 2013, during a meeting of the Sarasota Crew, including approximately 150 youth members, four gunshots were heard from the Betts' property, court records said. The next day, in an effort to allegedly intimidate wedding guests, Dickey Betts watched the Sarasota Crew practice with two firearms leaning against his chair.

Other incidents included the Betts' playing electric guitars, blowing air horns, and shouting obscenities at guests on the Bay Preserve property.

The Betts also allegedly made threats disrupt the Palm Ball, The Conservation Foundation of the Gulf Coast's largest fundraiser of the year, court documents said. The foundation is the owner of the Bay Preserve.

A judge issued a temporary injunction (restraining order) Feb. 6, 2014 to prevent the Betts from disturbing the "Palm Ball," which was held Feb. 8, 2014.

The Sheriff’s Office said Betts is expected to make her first appearance in court at 1 p.m. Wednesday. She is being held at the Sarasota County jail without bail.
