Alleged Parade Shooter Lyndell Mays Appears In Court In Shackles

Lyndell Mays -- the man who cops say fired the first gunshots at the Chiefs' Super Bowl parade last week -- appeared in a Missouri courtroom on Wednesday for the first time since he was hit with a murder charge over the shooting during the K.C. celebration.

Reporters inside of the courtroom say the 23-year-old showed up to the proceedings in an orange jumpsuit ... with shackles around his waist and feet. They added he also had a piece of white gauze taped to his face -- presumably covering wounds he suffered amid the chaos on Feb. 14 at Union Station.

Cameras were not allowed in the courtroom.

Mays did not enter a plea at the hearing ... and he's now due back in court for a bond review next Thursday. He remains in police custody on $1 million bail.

As we previously reported, Mays is facing one count of murder in the second degree, two counts of armed criminal action, and one count of unlawful use of a weapon ... after police say he admitted to firing his gun multiple times following a dispute with other people at the K.C. party.

Cops say Mays told them his actions were "stupid."

"Just pulled a gun out and started shooting," police said he told them. "I shouldn't have done that. Just being stupid."

One other adult, Dominic Miller, and two juveniles have also been hit with criminal charges related to the shooting. It's unclear when their first court appearances will take place.

More than 20 people in total were shot after gunfire erupted at the rally ... and one -- 43-year-old Lisa Lopez-Galvan -- lost her life.
