A Bay Ridge man out walking his dog was struck and killed by a teen driver on Fourth Avenue Thursday night, police said.

Frank Decolvenaere, 66, was walking westbound in the crosswalk of Fourth Avenue and 101st Street around 7 p.m. when he was struck by the 19-year-old driver of a Mercedes sedan, who was heading south on Fourth Avenue and made a right turn onto 101st Street.

Decolvenaere was pronounced dead at the scene.

The driver, who police did not identify, remained at the scene. No charges were filed and the investigation was ongoing.

According to a preliminary investigation, the NYPD said Decolvenaere crossed against the light.

Some reports said the driver was speeding, though police could not confirm that detail.

Decolvenaere was a friend to at least one of Bay Ridge Councilman Justin Brannan's staff members, who said he was simply out walking his dog. One source told Streetsblog that the "blood-covered dog ran about 10 blocks home after the crash, alerting Decolvenaere’s wife that something was wrong."

Police said Decolvenaere's dog was not injured.

Councilmember Brannan condemned reckless drivers in his district as a "scourge":

“Out of control speeding and reckless driving have been a scourge in Bay Ridge for far too long," Brannan said in a statement. "Some people drive like there are no laws and have total disregard for the safety of others. As we mourn the loss of Frank, let’s all think about how this happened and how those of us who drive can do our part to make sure it doesn’t happen again. Speeding to save a few seconds is a selfish way to drive and shows utter lack of consideration for our neighbors on foot. This reckless behavior must stop.”

Decolvenaere is at least the 24th pedestrian death in the city this year according to the NYPD.
