He opened fire as people left an Illinois restaurant. It took a jury 3 hours to convict him of the double murder.

A man who opened fire as people left an Illinois bar will spend the rest of his life behind bars.

Serafin Castellanos was convicted this month of a double murder in Kane County, Illinois. A jury deliberated for about three hours before handing down the conviction, according to media reports.

Castellanos is set for sentencing in February but faces a mandatory life sentence, according to Fox 32.

On March 10, 2017, Castellanos had a handgun when he approached Jermaine Taylor, 35, who had just left La Flama de Oro restaurant and bar in Aurora, Illinois, according to Fox 32. Castellanos fired a single shot, hitting Taylor in the torso.

Castellanos then ran away and fired eight more shots, Fox 32 reported, and hit Anselmo Fernandez, 57. Both Fernandez and Taylor were pronounced dead at the scene. A third person was also shot but survived the ordeal.

"This was an indiscriminate and intolerant act of violence in the community that we will not stand for," said Kane County Assistant State’s Attorneys Bill Engerman, according to Fox 32.

Police investigated and it wasn’t until 10 months later that they went to arrest Castellanos, according to Patch. When task force members found him trying to leave his car, Castellanos tried to flee but was caught.

"My thanks to the Aurora Police Department for working with us to organize the evidence we presented to the jury. They conducted a thorough investigation that did not end when we charged Mr. Castellanos,” Engerman said, according to Patch.

The jury convicted Castellanos of two counts of first-degree murder, aggravated battery and aggravated discharge of a firearm.
