MEMPHIS, Tenn. — A local man has been found guilty in the first-degree murder of a convenience store clerk.

According to prosecutors, Marico Vales and two other defendants robbed the Zorro Market on East Shelby Drive, leading to the death of 30-year-old Khaled Khayat in June 2015.

In addition to being convicted of first-degree murder, Vales was also found guilty of especially aggravated robbery.

The Shelby County District Attorney’s Office said he will be sentenced to a mandatory life sentence for the murder and a minimum of 15 years for the robbery.
