Three men were found guilty on Thursday of killing a robbery co-conspirator in Long Beach in 2010, according to the Los Angeles County District Attorney’s Office.

Luis Orozco, 37, Shawn Verrette, 42, and Frank Ervin, 53, were found guilty of first-degree murder, second-degree robbery and conspiracy to commit a crime, following a weeklong jury deliberation.

Jurors also found true a special circumstance allegation of murder during the commission of a robbery, as well as a gun allegation, the district attorney’s office stated.

A fourth defendant, Rosa Orozco, 39, pleaded no contest in September 2013 to being an accessory after the fact. She was sentenced to three years of summary probation in January 2014.

Authorities said on Monday, August 9, 2010 the victim, Lake Elsinore man Franklin Robles, arrived at a Long Beach bodyshop where he planned to rob its owner with Luis, who instead plotted with Ervin and Verrette to rob and kill Robles, according to Deputy District Attorney Karen Brako, who prosecuted the case.

As Robles waited for Luis, Verrette and Ervin appeared at the business, exited their vehicle and fatally shot Robles, Brako stated.

After the killing, Luis, Verrette and Ervin went to Robles’ home and stole his property, according to the prosecutor. Not long after the crime Rosa threatened a witness, the prosecutor added.

The three defendants will be sentenced on February 4 at the Long Beach Superior Courthouse. The men face a possible maximum sentence of life in state prison without the possibility of parole.

The case was investigated by the Long Beach Police Department.
