Young mother and her boxing-champ brother plummet from Bronx overpass in icy multi-car pileup

Jeneffer Sosa, 21, was killed. Her 20-year-old brother, Golden Gloves champion Pedro Luis Sosa, 20, was in a coma, relatives said.

The brawler, who narrowly missed a spot on the 2012 Olympic team in August, was about to turn pro Monday.

“It was supposed to be a big day,” said Sosa’s boxing coach, Marco Suarez.

Instead, family and friends gathered to mourn the loss of Jeneffer Sosa and pray for her brother. “Everybody’s crying,” Suarez said. “Everybody's waiting to see if he's going to live, or if he's going to die."

The Sosas were among 10 people packed into a Chevy Venture traveling east on the Cross Bronx Expressway about 5:45 a.m. Sunday as temperatures hovered near freezing and road surfaces turned treacherous.
