UPDATE TUESDAY 1:38 P.M.: Two children injured in the crash Tuesday morning have died, according to the Marion County Coroner.

Sandile Ncube, 12, and Malia Siziba, 5, died after crews rushed them to Riley Hospital for Children just before 8 a.m.

The coroner previously identified the driver who was killed as Norris Ncube, principal at Indianapolis Junior Academy.

The school identified the other three children who were injured as Buhlebenkosi Anita Nikoma, Deon Sizba and Jessica Senele Ncube.

Ncube, 50, frequently picked up his students in need of a ride to school.

Ncube was taking his own two children, along with three other students, to school that day when an SUV — which police said was speeding and driving erratically — struck the vehicle, killing Ncube and two children.

The school was in mourning on Tuesday.

Indianapolis Junior Academy is a Seventh Day Adventist private school that serves pre-kindergarten through eighth grade.

School officials described Ncube as an education innovator.

“He was able to increase enrollment and double it,” said Colleen Kelly, a communications specialist for Indiana Conference of Seventh Day Adventists.

Kelly said three of the students riding with Ncube this morning were sixth-graders at the school, along with one first-grader and one eighth-grader. Two of the children were Ncube’s.

“We are all in shock,” Kelly said.

EARLIER:

Two cars crashed during rush hour Tuesday morning, killing one man and seriously injuring five children and an adult, police said.

Three children remain in critical condition, while one is in serious condition, and another, stable, Wayne Township Fire Capt. Mike Pruitt said. One adult was rushed to the hospital in serious condition.

The vehicles crashed just before 8 a.m. on Washington Street, near the intersection of High School Road.

The intersection sits just west of I-465, adjacent to an entrance ramp, in Wayne Township.

All five children were in one car, a silver Honda SUV, along with the deceased driver. The driver of the second vehicle, a gold Ford SUV, is hospitalized.

It was not immediately clear if all the children were related.

A witness told investigators the driver of the gold SUV was speeding and driving erratically when it collided with the silver SUV, an Indianapolis Metropolitan Police press release said.

The gold SUV was heading west on Washington Street, approaching the intersection with the I-465 exit ramp. The silver SUV was following a green light into the intersection when it was struck by the gold SUV, police said.

Authorities will test the driver’s blood for intoxicants, as is standard procedure, police said. Investigators are also looking into whether the driver of the gold SUV suffered a medical issue, IMPD Sgt. Kendale Adams said.

The crash triggered a mass casualty response, with at least a dozen police and fire personnel responding to rush the six surviving patients to local hospitals

The badly damaged silver SUV that had carried the deceased driver and five children remained at the intersection while investigators processed the scene. It was resting partially in a grassy median.

Police have not released the names of anyone involved in the crash.
