A mother and her adult daughter were found dead in their Bronx home, bound with duct tape and with signs of trauma to their bodies, police said.

Police found the bodies of 55-year-old Ida Randolph and 21-year-old Jena Randolph in separate bedrooms in their apartment on Valentine Avenue Thursday evening. 

Neighbor Fatima Diallo said a young man knocked on her door at about 6 p.m. Thursday, begging to use her fire escape to get into his mother's apartment. She said he told her he was worried something was wrong.

"The guy came in, go by the fire escape and went to the room. One minute later, he came out, 'Oh my God, I just saw my sister laying down, I think she is dead,'" she said. 

They called 911 and fire crews broke down the door. It's not clear how long mother and daughter had been dead. 

"They were really good people from what I know," said neighbor Nijurlya Beasely. "Every time I saw the girl, she was always smiling." 

Investigators are questioning Jena Randolph's boyfriend, who may have recently lived with her and her mother, according to neighbors.
