Four Months Later, an Unsolved Murder at a N.J. Water Plant

Detectives narrow suspects down to plant employees, but surveillance cameras give no clues


Many of Angara's co-workers refused to discuss the case, citing the ongoing investigation. Left unsaid was the knowledge that - at least, according to prosecutors - the killer could be someone at the next desk.

"She was a nice lady, very friendly to everybody," said Indrakumar Patel, one of Angara's co-workers. "That's all I can say."

Angara's death has left a painful void in her family.

"My 9-year-old niece asked, 'What should I do for Mother's Day? I don't have a mother anymore,' " Rao said. "I had no answer for her. Then when I cry, she ask me why I'm crying. I tell her something got in my eye, but she knows I'm lying. She keeps saying, 'Why were they so unfriendly?' "

Avigliano said investigators are still working the case, re-examining evidence and seeing if they missed anything. He said the best chance for a break in the case will be "if someone gets an attack of conscience and confesses, or if someone who knows something comes forward. So far, neither of those things has happened."
