A Bronx high school football star was slain when he and his father brawled with parking attendants the accused of stealing a gift from their car just minutes after graduation, police sources said.

Isayah Muller, 19, a Truman High School graduate who led the school to the city championship last fall, had just left the ceremony at Lehman College with his mother, father and girlfriend headed for a dinner on City Island.

They pulled out of the parking lot on Jerome Avenue about 4 p.m. and the father turned around to confront the parking attendants about the missing cologne, a gift for his son and began fighting.

Both attendant pulled out knives and stabbed Isayah, 19, twice once in his side and once in his chest.

The critically injured Muller was rushed back into the car and the family sped to a nearby clinic which transfered him to Saint Barnabas Hospital, where he later died.

The parking attendants and his father were taken to the 52nd Precinct where no charges were filed.

Isayah, was slated to attend Nassau Community College in the fall and ran for a remarkable 290 rushing yards scoring a pair of touchdowns.
