Police are looking for a driver, possibly a cabbie, who pulled up and fatally shot a man who was waiting for a cab Monday.

The shooting occurred before dawn in front of Mexico Car Service at 203 South Broadway. Police said the victim, 35-year-old Jerome Hancock, was waiting for the cab when someone who might have been driving a blue taxi came from around a corner and shot him in the chest.

The victim's wife and five children gathered at the scene where a makeshift memorial is taking shape. "That's not right what he did ? the guy who shot my daddy," said Brittney Hancock, 9. "He took another kid's dad, it's not right."

According to Jessica Hancock, the victim's wife, police told her the victim had a dispute over a fare with a driver a few weeks ago. Hancock worked in food services at the White Plains Hospital Center.

The murder follows another taxi-related killing that took place early Sunday. Police said cabbie John Alli, 46, was traveling on Riverdale Avenue honking his horn at around 5 a.m. After he stopped the car, several people approached the vehicle and saw the dying driver?s throat had been slashed.

The incident involving John Alli occurred close to the site where another driver was killed in May. Geraldo Guitierrez, 29, was fatally stabbed after taking a Tuckahoe teenager to Yonkers.
