A Key West jury convened for about two and half hours Friday afternoon before finding Pablo Solano Jimenez guilty of first-degree murder in the 2010 bludgeoning death of Tracy Heshmaty.

Jimenez also was charged with robbery with a deadly weapon, but jurors found him guilty of the lesser charge of petty theft. Circuit Judge Mark Jones will sentence Jimenez on July 26. He faces life in prison.

Prosecutors allege Jimenez, 29, hit 37-year-old Heshmaty in the head with a rock while they were arguing in the early morning hours of May 31, 2010, in a parking lot behind First State Bank on Simonton Street.

Both were seen earlier on video surveillance cameras buying beer at a Truman Avenue pharmacy. They left the store within minutes of each other, according to an arrest affidavit.

Using a witness description of Jimenez and the video footage, detectives found Jimenez at a convenience store at the corner of Angela and Duval streets.

Jimenez told police he and Heshmaty went to his trailer on Simonton Street to have sex, after which she left.

Detectives searched the trailer and found spattered blood on a bicycle, and clothes in a nearby trash can that matched what Jimenez was wearing in the pharmacy video, Assistant State Attorney Mark Wilson told jurors in closing statements.

He also placed a 21-pound rock, the murder weapon, in front of jurors during his closing.

Assistant Public Defender Trish Docherty described a bungled police investigation in her closing statement, in which she said detectives failed to collect DNA evidence from at least five other potential suspects.

Earlier this month, Jones ruled that a confession made by Jimenez was admissible in trial.
