Alvin Wyatt, who is accused of firing a gun into the bleachers at a Pleasantville high school football game and killing 10-year-old Micah Tennent late last year, pleaded not guilty to murder and other charges Thursday.

WPVI-TV reports Wyatt did not speak during the brief hearing. He faces life in prison without parole if convicted.

Wyatt is charged with murder, two counts of attempted murder, and two weapons offenses. An Atlantic County grand jury returned an indictment against Wyatt earlier this month.

According to The Philadelphia Inquirer, Wyatt smiled at four women in the gallery as he entered the courtroom. His attorney entered the not guilty plea on his behalf.

After Wyatt’s appearance, Monica Tennant, Micah's aunt, said outside the courtroom, "I don’t understand why he’s coming out smiling like this is a joke. He took a baby’s life."

Prosecutors say Wyatt started shooting around 8:30 on the evening of November 15th in the home-team side of the stands at the Pleasantville High School football field during the school's game against Camden. Investigators say Wyatt was aiming at 27-year-old Ibn Abdullah but also struck Micah Tennant and a 15-year-old boy who was grazed by a bullet. Tennant died from his injuries several days later; the 15-year-old and Abdullah recovered. Numerous people were arrested in connection to the shooting. Multiple videos of the shooting and the ensuing chaos were posted on social media sites.
