The Citizens Voice newspaper reports Matthew Crane, 28, of Shavertown, Pa., informed authorities in 2015 about a scheme to defraud the casino of hundreds of thousands of dollars through free slots play with the use of duplicated player cards and personal information numbers.

At the time, Crane was working as a table dealer at Mohegan Sun Pocono.

His body was spotted by a passers-by Saturday afternoon floating in Mill Creek in Wilkes-Barre. One of the eye-witnesses who spotted the body told the Citizens Voice the dead man appeared to have a wound to his head.

However, no official cause of death ruling has been made. An autopsy conducted by forensic pathologist Dr. Gary Ross was planned for Monday.

In the casino fraud case, police in January 2016 charged Robert Pellegrini, a former casino vice president, and Mark Heltzel, a frequent casino patron, with theft and related charges in connection with the scheme, the Citizens Voice reports, adding:

At the time he reported the scheme, Crane was romantically involved with Rochelle Poszeluznyj, a beverage server at the casino who conspired with Pellegrini and Heltzel and was also charged, according to a police affidavit.
