NEW YORK – A high school football star was stabbed and later died hours after his graduation Tuesday in a fight with Bronx parking attendants over whether something was stolen from his family’s car during the ceremony, police said.

Isayah Muller, 19, a star running back who led his team to the Public Schools Athletic League championship, was rushed to a nearby clinic by his family and girlfriend and was later pronounced dead. No arrests have been made but the parking attendants and Muller’s father, Andre, were speaking to officers from the 52nd Precinct in the Bronx.

The family arrived at the lot on Jerome Avenue in the Bronx at 9 a. m. and walked over to the campus of Lehman College, where graduation was being held Tuesday for students from  Harry S. Truman High School. Following the ceremony, the family headed back to the car, police said.

An argument erupted initially between Muller’s father and parking attendants, whom he accused of stealing something from his car, police said. The father noticed the property missing from the car while the family was en route to a celebratory meal on City Island, a fishing hamlet on the northern tip of the Bronx.

Angry over the missing property, Andre Muller turned the car around and headed back to the parking lot. The fight broke out and Isayah Muller was stabbed in the chest, although it’s not clear by whom. The father and son ran to the family car where his mother and girlfriend were waiting and drove him to the clinic. Muller was later transported to a hospital where he was pronounced dead.

It’s not clear how many attendants were involved in the incident, or who delivered the fatal blow.

Muller was a star running back. He rushed for 285 yards during the high school championship game in November, winning 23-20 over the top seeded Beach Channel. His performance was the talk of newspapers and television. He was revered by his teammates.
