“Just seeing my mother lying there helpless, trying to think what was her last thoughts,” the victim’s daughter, Jeanette, told CBS 2’s Ann Mercogliano. “I know she had to have been afraid, but I hope whatever happened, happened quickly and she didn’t suffer much.”

Family members believe Hernandez was killed possibly over a flat screen TV and jewelry, items they claim are missing. Sources told CBS 2 that Velez is known to the family, has a drug record and may have stolen the victim’s TV to buy more drugs.

“I was just horrified to see her lying there, her face wrapped,” said Jeanette. “They had suffocated her and she was tied up.”

Julia Hernandez seemed worried on the phone just hours before her killing, according to Jeanette.

“She had called me and told me that someone in the building told her there was a suspicious character in the building,” she said.

When she went to check on her mom, that’s when Jeanette says she found her lifeless body.

“I told her be careful. That was the last time I spoke to her,” said Jeanette.

“Whoever killed her, you’re going to get it and we’re going to find you,” vowed her other daughter, Elaine.

Julia Hernandez was a grandmother of four and mother of two.
