It was a deadly weekend on New York City roads thanks to criminal drivers responsible for four fatal hit-and-run crashes.

The first took place in East New York just before 10 p.m., when the driver of a Ford Explorer allegedly sped through an intersection and smacked into a Toyota Sienna crossing in a perpendicular direction. The crash killed Saber Mohammed, 20, a passenger in the Sienna. The Daily News reports that Mohammed, a bodega clerk, was planning to fly back to his native Yemen next month to be married.

"He was an intelligent boy, and helpful," his cousin Hussain Mansour told the tabloid. "The whole family is in pain."

Mohammed's friend, who was driving the Sienna, survived but suffered neck and back injuries. The Explorer driver bailed, but cops caught up to Bronx resident Christopher Cates, 29, and charged him the following day with vehicular manslaughter, negligent homicide, leaving the scene of a crash, driving while high, marijuana possession, speeding, and failing to stop at a stop sign. Police also charged his passenger with marijuana possession.

Hours later, FedEx worker Giovanni Nin was headed to his girlfriend's house to rest before returning to work a 3 a.m. shift at the company's Castle Hill shipping center when police say the driver of a BMW SUV hit him on East Tremont Avenue near Mayflower Avenue.

"He was an employee but I treated him like a son," his supervisor Jeffrey Rodriguez told the News. "He would do anything for anybody. He’s the hardest worker I’d ever known."

The driver of the silver BMW X5 left Nin for dead and is still at large. Nin was reportedly saving up for a wedding.

Another driver struck near Battery Park City on Saturday evening, shortly before 8 p.m. The man behind the wheel of a Ford truck turned right off of West Street onto Chambers Street and ran into a woman riding a bike in the same direction, according to police. The driver fled, but an off-duty MTA cop caught up to him three blocks away, and officers arrested him. The driver, Samuel Silva of Newark, is being held without bail at the Tombs in lower Manhattan and facing charges of vehicular manslaughter, leaving the scene of a crash, failure to yield to a pedestrian, and driving while intoxicated.

The weekend's fourth fatal hit-and-run occurred early on Sunday morning at around 1:19 a.m., when an SUV driver slammed into 62-year-old Sharon Smith as she tried to cross East Gun Hill Road in Williamsbridge. The driver never stopped, according to police.

A pedestrian in his 20s was also critically injured by a cab driver on the Upper West Side early on Saturday morning. The News reports that the victim was paralyzed in the crash.

In response to the slew of deadly crashes, the street-safety group Transportation Alternatives called for state legislators to pass legislation that would toughen penalties against hit-and-run drivers. Leaving the scene of a fatal crash is currently a Class D felony, punishable by as many as seven years in prison, but leaving the scene of a crash resulting in an injury is a misdemeanor, punishable only by a fine and a maximum of three months incarceration. First-offense drunk and high driving is punishable by as much as a year in prison, and New York prosecutors almost exclusively reserve vehicular manslaughter charges, punishable by up to 15 years, for drivers proven to have been impaired. It's hard to prove drunk driving, Transportation Alternatives director Paul Steely White said in a statement, when the driver is long gone.

"Under current law, drivers who may have consumed alcohol and are then involved in a collision have a strong incentive to flee, since the penalty for a DWI is currently more severe than the penalty for leaving the scene—an act that delays medical attention for victims
and undermines investigations," Steely White said.

Road-safety advocates often deem vehicular carnage "traffic violence," and whether or not one agrees with the rhetorical flourish, the casualty count is real. For example, from May 29th to June 5th of this year, the NYPD recorded 4,654 crashes on city streets resulting in 1,262 injuries and three deaths. During the same period, police logged nine murders, but the number of people injured by gun violence was just a fraction of those injured in crashes. Specifically, 33 people were injured in 28 shootings that week.

This weekend, four people died in shootings, all clustered within six hours on Saturday night and early Sunday morning.
