Hit-and-run drivers killed a pedestrian and a cyclist in Brooklyn and Queens this weekend.

Sunday night at around 9:30, a 40-year-old man riding a bike on Rockaway Boulevard near 90th Street was struck by the driver of a Mercedes van, according to reports. NYPD told the media the driver sideswiped the cyclist from behind and ran him over. The driver then stopped, exited the van to look at the victim, got back in and drove away, police said. As of this morning, NYPD had not released the victim’s name and the driver remained at large.

The cyclist was at least the fourth person killed by a driver while biking or walking in the 102nd Precinct this year, according to crash data compiled by Streetsblog, and at least the fifth pedestrian or cyclist killed by a motorist on Rockaway Boulevard since January 2013. Yesterday’s crash occurred in the City Council district represented by Eric Ulrich.

On Saturday morning, the driver of a Nissan Altima hit Felipe Castro Palacios, 27, on Third Avenue near Seventh Street in Gowanus, outside the auto repair shop where he worked, according to reports. From the Daily News:

Palacios was repairing a Ford Expedition parked halfway on the sidewalk in front of Samba Transmission & Auto Repair on Third Ave. near Seventh St. in Gowanus when a black Nissan Altima slammed into him and two parked cars at about 7:30 a.m., cops said.

The mechanic was hurtled head-first into the back of a parked Dodge Venture minivan, blowing the back window out, witnesses said.

Police identified the car as a rental but had not located the driver as of Sunday. The crash that killed Felipe Castro Palacios occurred in the 78th Precinct, and in the council district represented by Brad Lander.

This weekend’s victims were at least the fourth and fifth hit-and-run fatalities of the year. Starting in July 2015, NYPD will be required to report to the City Council on hit-and-run crashes and investigations. Of 60 fatal hit-and-runs investigated in 2012, NYPD arrested just 15 drivers, according to Transportation Alternatives.

A bill to toughen penalties against drivers who flee the scene of serious crashes cleared the State Senate in 2012, but did not pass the Assembly.
