A Columbus city engineer has died, more than two weeks after he was critically injured in a horrific Downtown crash that also killed an Ohio State intern.

Bill Lewis, 58, the city�s chief mobility engineer, was pronounced dead at 6:30 p.m. yesterday at OhioHealth Grant Medical Center, Columbus police said.

Lewis had been in grave condition, with one of his legs amputated immediately after the crash and the other recently amputated. He also had suffered major head trauma and internal injuries.

Stephanie Fibelkorn, 21, the Ohio State engineering student who died in the Dec. 12 crash, was an intern for Lewis. She was working her last day at the city engineer�s office on the day she was killed. The two were walking to a meeting when they were struck.

�Obviously, we are all very saddened,� said Dan Williamson, speaking on behalf of Columbus Mayor Michael B. Coleman last night.

�Everyone at the city has been praying for Bill. This entire incident has been heartbreaking for the city and the Department of Public Service,� he said. �We lost Stephanie and now we have lost Bill. Our prayers are with his family. He was an outstanding employee and a good friend.�

Lewis was one of the city�s �finest engineers,� said Rick Tilton, assistant director of the Department of Public Service.

�He was just a master of his craft. It�s not going to be the same with him not there.�

The way that people have rallied around the families of Lewis and Fibelkorn is �a good measure of what people thought of both of them,� Tilton said.

Surgeons at Grant Medical Center initially said that Lewis was �defying the odds� because he seemed to be rallying despite the extent of his injuries, Jennifer Hansen, a family friend, said in a prior interview.

The investigation into the crash continues and no one has yet been charged.

The Columbus police accident-investigation unit continues to interview dozens of witnesses who were at or near High and Broad streets the morning of Dec. 12, said Sgt. Brooke Wilson.

The crash happened about 10 a.m., when police say a pickup truck driven by Terrance Trent, speeding and weaving in traffic on E. Broad Street, went out of control and hit a school bus at the intersection of Broad and High.

The Groveport Madison bus, carrying a few special-needs students, was pushed onto the sidewalk where Lewis and Fibelkorn stood waiting to cross at the light. Both were crushed by the bus.

Trent, 61, and a passenger in his truck, Mamie Adams, 51, were injured, as was the bus driver, Brenda Detty. The students on the bus weren�t hurt.

Trent, in an interview with The Dispatch, said that Adams was hitting him with a can of pop while he was driving and he was trying to get to the police station. Her family has denied that.

Trent was treated at Mount Carmel West; Adams and Detty were both treated at Grant Medical Center and released.
