BRADENTON, Fla. (WWSB/Gray News) - A Florida woman is accused of killing both of her ex-husbands in two separate shootings on the same day.

According to Manatee County authorities, 48-year-old Susan Erica Avalon shot and killed an ex-husband in Manatee County on Wednesday afternoon, then another ex-husband in Tampa later that day.

Detectives say Avalon used stolen food from Panera Bread as a trick to get the Manatee County man to open his front door.

“When this victim opened the door, the suspect started to fire immediately,” a Manatee County Sheriff’s Office spokesperson said.

Authorities shared surveillance video showing Avalon walking into a Panera Bread about a mile and a half from the scene. Investigators said she took food from a delivery pickup shelf without paying, then headed to the victim’s home.

License plate readers tracked her silver Honda Odyssey from Citrus County to Hillsborough County, across the Sunshine Skyway Bridge into Manatee County, and back home after the shootings, according to investigators.

The Manatee County Sheriff’s Office held a news conference Thursday morning.

Court records show Avalon and the Manatee County victim had been divorced for about 11 years, with long-running custody disputes and about $4,000 in unpaid child support.

She faced a December deadline to pay $200 or lose her driver’s license.

When detectives arrived at Avalon’s Citrus County home, they said they found her cleaning the minivan with bleach and rags.

During questioning, when asked to discuss her ex-husband, Avalon replied, “Which one?”

That answer led investigators to ask Tampa police to conduct a welfare check at a residence on Frierson Avenue Wednesday night.

Officers found an adult man inside the home dead from multiple gunshot wounds, with damage to a rear door that appeared to show forced entry, authorities said.

According to Tampa police, they believe that this shooting is related to the Manatee County homicide investigation, with detectives saying the shooter and victim were known to one another.

Homicide detectives said they are working in coordination and have identified credible evidence indicating the cases are indeed related.

Both agencies are working with the state attorney’s office to determine what charges, if any, apply in the Tampa case.

Avalon’s live-in boyfriend told detectives she had recently tracked down the Manatee victim’s address. He said she also told him the day before the shootings that she loved him “in case something happens to her.”

Investigators said he told them that when Avalon came home after the shootings, she got into the shower still wearing the same gray sweatshirt seen in the surveillance video.

Records show Avalon was previously arrested on a child abuse charge in Virginia in 2004. Other child abuse cases included Tampa and Pasco County, which were dropped. Investigators said those cases were tied to custody disputes with her ex-husbands.

Avalon currently faces a second-degree murder charge in Manatee County.

According to prosecutors, they plan to seek a first-degree murder charge and the death penalty, while Tampa authorities are running a separate homicide investigation tied to the second victim.

Investigators noted that the case affects about five children from both marriages.

Avalon is currently in custody in Citrus County, as detectives continue to search her vehicle for evidence.

The coroner has not immediately released the names of the shooting victims.
