NEW YORK (CBSNewYork) — An investigation continued Wednesday into a chain reaction crash that left a mother dead and her 6-year-old son injured in Brooklyn.

Police said the two had just left a nearby home around 9 p.m. Tuesday and were standing at a bus stop near the intersection of Remsen and Seaview Avenues in Canarsie. An SUV traveling west on Seaview hit a sedan heading east that was trying to turn onto Remsen, causing the sedan to jump the curb.

“They tried to avoid each other and they hit,” said witness Michael Thomas. “They pinned the lady and the young boy up against the fence.”

The mom, identified as 33-year-old Shaena Sinclair, was pronounced dead at the scene. Her little boy, Jayvon, suffered a head injury and was listed in critical but stable condition.

“I can’t, I don’t sleep,” Sinclair’s mother told CBS2’s Andrea Grymes. “I love my daughter… I don’t know what to say.”

“That poor child doesn’t even know his mother is gone,” cousin Kamille Edwards said.

“It’s really unbearable for our family. We have to now raise a 6-year-old on our own. He has no mom,” cousin Sheneka Edwards added.

Diane Watkis-Forester lives in the house on the corner, where he fence was damaged.

“My husband built this. This is nothing. A life is lost,” she told Grymes. “A child doesn’t have a mom anymore. That’s the most shocking thing of all.”

People who live nearby said it’s not uncommon for drivers to zip along that stretch of roadway.

“They use this block as a speedway,” said Thomas. “When that light turns green from Avenue N to Seaview, it’s like a raceway. They do 80, 90 miles per hour.”

He said police from the 69th Precinct are often in the area writing tickets.

“This is not the first tragedy we had. The Department of Transportation very well knows that Remsen Avenue is a speedway. It’s been over three of four years, and nobody has done nothing,” he said. “They said they were going to look into it.”

Both drivers had the green light and stayed at the scene.

Sources told CBS2 speed did not appear to be a factor in the crash. No charges have been filed, since officials say it appears to be a tragic accident.
