"48 HOURS" INVESTIGATES THE SHOCKING MURDER OF FAMED LOS ANGELES HAIRDRESSER FABIO SEMENTILLI IN "WHO KILLED FABIO?"

Saturday, March 10 - 10:00 PM, ET/PT

Fabio Sementilli was a beloved hairstylist and beauty company executive living the good life in Los Angeles. That all ended when he was brutally murdered while relaxing near his pool. Why would anyone want to kill him?

Michelle Miller and 48 HOURS investigate the murder of Sementilli and the hunt for his killers in "Who Killed Fabio?" to be broadcast Saturday, March 10 (10:00 PM, ET/PT) on the CBS Television Network.

It is a case right out of a primetime crime drama, but it is real. After Sementilli was found stabbed to death, police scoured surveillance video from his Los Angeles neighborhood. Cameras caught the suspects on video running to his home - and then leaving in his Porsche 35 minutes later. While there was video, the suspects' identities are hidden.

Sementilli was described as larger than life in the hairstyling industry. He lived with his second wife, Monica, and their kids in a beautiful home. At first, police believed Sementilli was the victim of a notorious wave of crimes known as knock-knock burglaries, targeting Los Angeles celebrities. Knock-knock burglars had hit the homes of former Los Angeles Lakers star Derek Fisher, Nicki Minaj and Alanis Morrisette. These thieves typically stole cash and jewelry, but this was the first case where police initially tied a murder to knock-knock burglars.

Police would learn that the reason behind the murder was much darker and twisted than a simple robbery. Turns out, it wasn't a break-in gone wrong that led to Sementilli's death after all. Nearly five months later, a pair of arrests would shake Sementilli's family to the core.

"I'm like - they sure?" Sementilli's sister Mirella Rota tells Miller.

"That was a huge shock," Sementilli's friend Pete Castellano says.

"It was like a twist in a nightmare," says Sementilli's son, Luigi.

How did the respected businessman and industry icon end up a murder victim?

Miller and 48 HOURS investigate the strange case, which relied on DNA, revealed a love triangle and exposed an elaborate alibi through interviews with friends and family members, investigators and more.
