Dominguez said his mother went to pick up the baby but an emergency response person told her to stand back.
The apartment is in a relatively new building facing Jackie Robinson Park. A crowd of onlookers had gathered nearby Wednesday afternoon, awaiting the medical examiner’s office, which would determine the official cause of the woman’s death.
Resident Yaa Dwamena, 32, said she’s lived in the building for several years and as long as she’s been there she’s seen Wachenheim.
“She was very nice, very friendly, very warm,” Dwamena said.
She said that the last time she saw Wachenheim was last week.
“I wouldn’t have thought anything was wrong with her,” she said. “They were a happy-looking family. I wouldn’t think anything like this would happen.”
Wachenheim went to law school at Columbia University, and her father was a state police spokesman before his death in 2011. She worked in state Supreme Court in Manhattan doing legal research for judges, court officials said.
“We are all deeply saddened about this tragic incident,” state courts spokesman David Bookstaver said. “Our thoughts are with Ms. Wachenheim’s family.”
