TAMPA, Fla. (WFLA) — Michael Keetley, a former ice cream truck driver accused of killing brothers Juan and Sergio Guitron and wounding four others on Thanksgiving Day in 2010, was found guilty on all counts by a jury Tuesday morning.

Jurors began deliberating at 4 p.m. Friday, took an hour break, and then deliberated until 9 p.m. Friday evening before going home for the weekend.

Jurors were instructed not to speak to anyone about the trial over the weekend. They then reported back to court at 8:30 a.m. Monday to begin deliberations at 8:30 a.m.

Keetley had been tried for the murder before, but a previous jury was not able to reach a verdict.

Assistant State Attorney Michelle Doherty told jurors during her closing arguments that Keetley killed out of revenge.

“He started shooting them one by one by one,” Doherty said. “They were unarmed, they did what he wanted and he shot them anyway.”

The defense contends the men who were shot identified the wrong man and that the Hillsborough County Sheriff’s Office made many mistakes during their investigation.

“The investigation that followed was nothing short of a nightmare itself,” said Defense Attorney Richard Escobar.

The murder happened on Thanksgiving Day of 2010.

A previous trial in the case ended when the jury could not reach a verdict.

The brothers Juan and Sergio Guitron, better known as “Magic” and “Spider,” both died at their home on Ocean Mist Court in Ruskin.

Four other men were wounded but survived.

Prosecutors said Keetley was actually out to kill a man he knew as “Creeper” and thought that man was in the group on the night of the shooting.

Prosecutors said Keetley was out for revenge on the night of the shooting because he had been robbed and shot while driving his ice cream truck.

The state said Keetley then became obsessed with finding the man who shot him and conducted his own investigation and then shot the men he thought were responsible
