Lawsuit filed against city in double murder case

Two friends murdered in their Phoenix home, the crime has been unsolved for more than five years. And now the family of one of the victims believes they may have a strong lead, and they are suing the Phoenix Police Department to get answers.

The mother of Nicole Glass claims she has info that may show her daughter was working as a confidential informant for the Phoenix Police Department, and the department failed to protect her. She believes her daughters murder was a hit.

It's been unsolved since 2010, the murders of Nicole Glass, Melissa Mason, and Mason's unborn child. The roommates were strangled to death in their Phoenix home and police never determined a motive. But Rachel Glass never gave up.

"People have moved on, but I haven't because I can't let go of this until I find out the truth, my daughter deserves that," said Rachel Glass.

Glass says she recently received information that her daughter may have been a CI for the department. The 27-year-old was involved in a large drug, conspiracy, and money laundering case. But the family doesn't know exactly who she may have been talking to police about.

"I believe this was a hit on my daughter," said Glass.

In a lawsuit filed Tuesday morning, attorneys claim Nicole was used to gather information about the criminal activity from dangerous individuals.

"We believe there will be information that comes to light that indicates police did not take adequate steps to protect her. At this point though the lawsuit will enable us to find out more information, it gives the gateway to finding out what really happened. There are individuals in the police department that know the details of her work for them," said attorney Scott Halverson.

For Rachel Glass, who has held vigils and waited years for answers, this may be her best lead yet.

"I hope that it opens the door to finding the answers about the circumstances surrounding my daughter's death, somebody needs to be held accountable for this," she said.

Phoenix Police issued the following statement: "The Phoenix Police Department has been aggressively investigating this homicide since it occurred in 2010. Although the case remains open, to date, investigators have not found any evidence to support this recent claim. The Phoenix Police Department will remain focused on the facts surrounding this case, and we are committed to solving this crime."

In the lawsuit, Glass is seeking damages, but she says this is more about getting answers and finding the killer rather than money.
