Mystery Surrounding Rio Casino Manager Murder Profiled on Dateline

The mystery surrounding the 2004 unsolved murder of a Niagara Falls native in Las Vegas was profiled on Dateline Investigation Discovery.  The episode was originally aired in 2011 and rebroadcasted and repackaged as "new" to the Investigation Discovery channel at 9 pm EST and re-airing at Midnight Eastern Standard Time.  Re-airing May 13 3 pm ES

The body of 26 year old Theresa Insana was found in November 2004 in a drainage ditch at a construction site in Las Vegas. She had been working as a manager at the Rio Casino and Hotel after moving from Niagara Falls. Police found there were bloodstains in her home and on her car.

Her father Joe Insana said his daughter had a special way of connecting people and often tried to help them with their problems. But he says she had been depressed in 2004 following the break-up of her engagement to a casino co-worker. That was months before the murder.

Insana says he feels Las Vegas police detectives thoroughly investigated the case as they interviewed numerous people and even went through her diary for clues. Insana says they also collected DNA evidence but there were no arrests.

Joe Insana says police were also puzzled by the scene in her home. He says nothing was taken including jewelry and money. They also told him there were no signs of forced entry so she apparently knew her attacker and allowed that person into her home.

Insana hopes the Dateline program will help prod someone to come forward with information to solve the murder of his daughter.

While they wait for a solution, the Insana family has also tried to keep her memory alive with a special scholarship program. A benefit concert for that program will take place Thursday evening, July 14th at the Rapids Theater in Niagara Falls.
