Driver's road riddled with wrong turns
The accidentÂ that killed a pregnant NYPD traffic agent was Walter Walker's worst alleged misdeed - but it was far from his first.
His history of recklessness dates back to at least 1986, when he fired a gun on a Harlem street for no apparent reason, according to court records.
When he got caught, he tried to stash the weapon in the clothes of an 8-month-old baby, police sources said.
Walker was busted again in 1993 when he and two buddies tried to scam a 62-year-old woman out of $9,000 worth of savings in an investment scheme, police sources said.
He was arrested on charges of grand larceny and possession of stolen property but pleaded guilty to a lesser count of fraudulent accosting. In March 1993, was sentenced to five days' community service.
Walker was in trouble again in 2003 when he threatened to bash a neighbor in the head with an aluminum baseball bat. He chased the man up and down W. 139th St. until cops arrested him on charges of menacing and harassment.
Again he pleaded guilty to a lesser charge - disorderly conduct - and was told it would be dismissed if he didn't get into trouble and attended an anger management class, sources said. It was unclear if he ever did.
Walker didn't pay any attention to the laws of the road, either. He has driven without a legitimate license since 1989, when he got his first of two dozen suspensions.
He was arrested in August 1999, when he was caught in a traffic checkpoint driving without a license. He was busted again for the same thing in 2005 and convicted in 2006.
Now charged with criminally negligent homicide, Walker, 72, blames the accident on bad breaks, said defense attorney Michael Torres. "My client is absolutely remorseful. He said he tried to repair the brakes," Torres said in court.
Walker's wife, Yvette, said her husband's life is full of good deeds. "He's no villain," she said.

A MTA Bus 
A seven-month pregnant New York City resident was killed after being run over by a bus. 

33-year-old Donnette Sanz, a traffic agent for the city police department was crossing a Bronx intersection at East 188th Street and Webster Avenue when a van pushed her into the path of an oncoming school bus that then pinned her to the road.

"We was riding along, coming down the hill," John Dargan, a passenger in the van, told the Daily News. "He said, 'Oh, my Lord, I don't have no brakes.' It happened so quick."

Approximately 30 people helped lift the bus off of the woman. "I ran out of my house to join 10 people trying to lift up the bus," said Cheryl Brown, 47. "At first, we couldn't get it up, so then another 10 people ran over to help, and we got the bus up and the lady out."  After being freed from beneath the bus, Sanz was then transported to St. Barnabas Hospital where her baby was delivered by caesarean section.

Sanz survived the birth, but died an hour later. The 1.5kg boy, named Sean Michael, was initially classified as being in critical condition, but later showed signs of improvement.

"The light turned red, and I couldn't stop. I tried to miss her," said the van's driver, 72-year-old Walter Walker, to the New York Post. Walker was arrested on charges of criminally negligent homicide and driving without a license. He pleaded not guilty. Police said the brakes on Walter's van were in such poor condition that the vehicle was unsafe. Police Commissioner Raymond Kelly said that Walker already had 20 suspensions on his driver's license.

Mayor Michael Bloomberg offered condolences to Sanz's husband, Rafael. "It's a terrible poignancy that Donnette's son's birthday will now coincide with the day his mother died," Bloomberg said in a statement.

Sanz's colleagues have set up a memorial at the intersection where she was killed.
