"48 HOURS" INVESTIGATES TWO SEPARATE MURDERS THAT RIPPED FAMILIES APART, IN A SATURDAY NIGHT DOUBLE FEATURE

Saturday, August 22, 2015 at 9:00 PM, ET/PT

The 48 HOURS team takes on two separate murder mysteries in a Saturday night double feature to be broadcast August 22, 2015 (9:00-11:00 PM, ET/PT) on the CBS Television Network.

Peter Van Sant and 48 HOURS investigate the murder of one-time millionaire Lanny Horwitz, who was shot nine times and left in a pool of blood in the bathroom of his Jupiter, Fla., home, in an updated encore of "Love, Hate & Obsession," to be broadcast at 9:00 PM. Horwitz's ex-wife, Donna, who was supposedly reconciling with him at the time, was in the connected bedroom. Radley, his son, a former gun dealer, was also in the home.

The police investigation uncovered a deeply troubled family struggling with debt, a father with an unusually close relationship with his female business partner, and a patriarch who allegedly was hard on his son and his ex-wife. Donna Horwitz was eventually charged with murder, but at trial, her defense attorney argued Radley had the motive to kill his father. Then, just when it seemed the case was closed, a courtroom twist changed everything.

And at 10:00 PM, Troy Roberts and 48 HOURS look at the case of a young mother who was murdered more than two decades ago and the Facebook-savvy police officer who took on the investigation, even though he had never worked a homicide case, in an encore of "Decades of Deceit."

Amy Weidner was beaten, sexually assaulted and killed in the bedroom of her Indianapolis home while she and her 2-year-old daughter were home alone on Nov. 13, 1989. She was found by her mother, Gloria Weidner, who returned to the house after her daughter couldn't be reached by phone. At the time of the murder, Gloria was sure police would see they were a good family and find the killer. There was a bloody handprint on the bedroom wall. Police believed Amy was killed by an acquaintance and chased down many leads, none of which led to an arrest. And then the case went cold.

The Weidner's case eventually landed in the Indianapolis Metropolitan Police Department's cold case unit. In 2011, in response to a newspaper article about the case, friends created a "Remembering Amy Weidner" Facebook page. The detectives in the cold case unit were not well-versed in using Facebook, but knew a colleague who was: Detective Sgt. William Carter, a nuisance abatement officer. They asked Carter for help printing some pictures from the Facebook page. In the process, he became obsessed with helping the family solve the crime.

He jumped on the case using his own time, and soon found a lead others had missed. The stunning revelation would send the investigation on a path no one expected. But would it provide the family with some long overdue answers?
