JACKSONVILLE, Fla. -

A woman who prosecutors said helped plan the robbery of a Gate gas station last May and was the lookout for her boyfriend, who was shot and killed by police, has been convicted in the fatal robbery.

Shaketa Jones, 28, was found guilty of robbery and felony murder in the robbery of the gas station in the 8000 block of Atlantic Boulevard.

Undercover police shot and killed 28-year-old Jesse Cooper, who police said was in an SUV and pointed a gun at the officers who had the place staked out after several other Gate gas station holdups.

A Jacksonville Sheriff's Office response to resistance board determined that the two officers acted within departmental regulations for the use of deadly force.

Jones was arrested at a nearby parking lot shortly after the shooting. She claimed she was having phone sex with Cooper at the time and wasn't an active participant, prosecutors said.

Prosecutors said that because Jones was an accomplice, she was held legally responsible for her boyfriend's death.

The jury convicted her in less than 30 minutes. She could get life in prison when she's sentenced in March.
