An MS-13 gangster was found guilty on Thursday of conspiring to kill a man for wearing a No. 18 Peyton Manning jersey.

Jose Suarez, also known as “Chompira,” was convicted on murder, racketeering and assault charges for the Jan. 29 killing of Esteban Alvarado-Bonilla in a Long Island deli, according to federal prosecutors.

The gang member was also convicted for a violent 2016 attack in Brentwood.

“Suarez has been held responsible for the execution-style murder of a suspected gang rival and violent assaults, ruthless crimes that reflect the danger to our communities posed by MS-13,” US Attorney Donoghue said.

“By his actions the defendant sought status within the gang, and with today’s verdict, what he has found instead is a mandatory sentence of life in prison.”

Suarez, 24, was trying to earn his stripes for an MS-13 affiliate when he served as the getaway driver in the slaying, the US Attorney’s Office for the Eastern District of New York said.

He also communicated with gang leaders as the shooter walked into the El Campesino Deli in Central Islip shot Alvarado-Bonilla in the head.

The victim was “marked for death” because he was wearing a Manning number 18 jersey, and was suspected of being part of the rival 18th Street gang, prosecutors said.

A bullet that went through the man’s head hit a female deli clerk, who survived.

Suarez’s lawyer had claimed that the assault was a “stupid fight amongst a bunch of young, dumb men” and not gang-related.

He faces a mandatory life sentence for the conviction.
