DID THE PRESSURE TO CLOSE MORTGAGES DRIVE A LOAN OFFICER TO MURDER HIS CLIENTS? CBS "48 HOURS MYSTERY" -- SATURDAY, NOV. 22

For nearly a year Renee Ohlemacher was suspected in the murder of her parents, Bernadette and Greg, who were shot in their Albuquerque, N.M. home in August 2005. Renee says, upon hearing the gunshots, she squeezed herself into a closet and called the police. Certain that the killer knew the couple, investigators began questioning Renee's every move after discovering that she did not immediately dial 911, opting to call a non-emergency number first. And her family had their doubts about her innocence too. Renee, who some family members considered spoiled, was set to inherit nearly $1 million from a life insurance policy. Her questionable behavior the morning of the murders and her cold demeanor in their wake did nothing to quell their suspicions. But with no physical evidence linking Renee to the crime, the probe began to stall, until a chance encounter would expose the unlikeliest of suspects - the couple's mortgage broker, Ron Santiago.

Santiago, a self-proclaimed people pleaser, was facing mounting pressure to close loans and eventually turned himself in to the Secret Service, admitting that he forged two checks when he could not deliver on a loan. But as the Secret Service dug into Santiago's past, their investigation would reveal something more serious. Did the stress of his job drive Santiago to murder?
