Detectives first suspected the involvement of a local crime ring known as the "Knock Knock Burglars," notorious for targeting affluent neighborhoods in Los Angeles. These burglars were known for their swift, efficient robberies, often targeting homes with valuable jewelry and cash.

5. Emergence of Robert Baker as a Suspect

As the investigation progressed, discrepancies emerged that pointed away from a simple burglary. Notably, Fabio's expensive Rolex remained on his wrist despite the chaos, and the security footage's DVR was missing—raising suspicions of premeditation. A breakthrough came when a neighbor's security camera captured two hooded men leaving Fabio's home in his Porsche. Further investigation identified one of these individuals as Robert Baker, a racquetball coach with a dubious past, including a conviction for lewd acts with a minor.

Her seemingly out-of-character behavior post-murder, including lavish spending and an affair with Robert Baker, raised red flags. Surveillance revealed that Monica and Baker were communicating in codes and acting suspiciously, leading authorities to suspect her involvement in orchestrating the murder for financial gain through Fabio's life insurance.
