Samuel Cohen Eckstein, a 12 year-old boy about to celebrate his bar mitzvah, was killed yesterday at the intersection of Third Street and Prospect Park West in Park Slope. NYPD says the crash investigation is ongoing and as of now there are no arrests or summonses for the driver who ran him over. Although police would not release information about the driver, NYPD said that “preliminary results” show that Cohen Eckstein “ran into the street.”

The Daily News reports that Cohen Eckstein was bouncing a ball off a monument at the entrance to Prospect Park, across the street from his home, at about 5:15 p.m. yesterday when the ball rolled into the street and he chased after it. NYPD says that Cohen Eckstein suffered trauma to his torso and was taken to Methodist Hospital, where he was pronounced dead on arrival.

Cohen Eckstein was hit by the driver of a white 2006 Chevrolet van belonging to New Wave Design of Sunnyside, Queens. Photos and reports from the scene indicate the driver was moved to the back seat of an NYPD cruiser after the crash, but he was later released. NYPD would not release the identity of the driver of the van; Streetsblog’s calls to New Wave Design have not been picked up and lead to a full voicemail box.

Park Slope Stoop reports that Cohen Eckstein was planning to celebrate his bar mitzvah next month.

Cohen Eckstein’s parents, Gary Eckstein and Amy Cohen, spoke at community meetings in support of traffic calming and the protected bike lane on Prospect Park West. “I like to pick up my kids from Hebrew school on my tandem,” Eckstein said at a 2011 community board meeting about PPW. “Before it wasn’t safe, but now I can do it.”

“The city feels much safer than when we started,” Cohen said in a 2008 Los Angeles Times article about bicycling in New York.

Eckstein was also interviewed for a 2008 New York Times article about malfunctioning pedestrian signals. “My kids have been noticing them around Park Slope,” he said, noting that some pedestrian signals do not work properly during the walk phase. “Although confusing, it is probably not as dangerous as it could be.”

Motor vehicle crashes are the top injury-related killer of New York City children, according to the Department of Health. At least eight children aged 12 and under have been killed by NYC motorists in 2013, according to crash data compiled by Streetsblog. Three of those victims were killed since September 26.

“Heart broken by incomprehensible loss of Sammy Cohen Eckstein,” Lander said on Twitter. “Beautiful kid & family. No words.”

Speaking at the CityLab conference yesterday, NYPD Commissioner Ray Kelly suggested that traffic crashes are too “complex” for police to hold reckless drivers accountable. “You’re going to have a lot of traffic,” Kelly said. “And you’re going to have accidents.”
