Valessa Robinson, who as a Tampa teenager in 1998 became infamous for the role she played in the murder of her mother, is scheduled to be released from a south Florida prison.

According to the state Department of Corrections, Robinson will be released on Friday from the Homestead Correctional Institution in Miami-Dade County.

In 2000, a Tampa judge sentenced Robinson to 20 years in prison for third-degree murder in the death of her mother, Vicki Robinson, plus grand theft of a motor vehicle.

Vicki Robinson was a 49-year-old real estate agent when she was murdered in her Carrollwood home. Valessa Robinson was 15. Robinson, her boyfriend, Adam Davis, 19 at the time, and another friend, Jon Whispel, teamed up to kill her.

Jim Iverson, with the Hillsborough County Sheriff’s Office, was a detective on the case in 1998, and remembers interviewing both suspects.

“He tried to cover up for Valessa originally. They were in love. Mom didn't want them to be together. That was their whole thought process, for them to be together," he said.

According to state records, the three hatched a plan to kill Vicki Robinson, then went to the home with a syringe Davis bought. They put her in a sleeper hold and injected her with bleach. When that didn't kill her, Robinson stabbed her multiple times, state records show.

Almost a week later, the teens were arrested in Texas. Vicki Robinson's body was found in a garbage can in the woods near her home.

Two of Vicki Robinsons’ best friends say they have no ill will toward Valessa for the murders- only hope that she will turn her life around.

Deborah Sartor Englert and Ed Philipps remember listening to Vicki just before her death as she worried about her troubled 15 year old and Valessa’s new boyfriend Adam Davis.

“Her daughter Valessa had basically forewarned her that she would be harmed of she did not cooperate,” said Englert. “I don’t think any of us thought that would mean being killed seven days later.”

“Maybe there will be a day when I could speak with her. I'm open to that. I don't know about tomorrow. I've forgiven her years ago,” said Philipps. “If you don't forgive a senseless act like that, you become a prisoner too.”

Davis is on death row. Whispel was sentenced to 25 years and is currently scheduled to be released in 2020.
