Olukayode A. Owolabi, 27, a jewelry and fashion designer, was fatally shot on January 16, 2019, in Palmdale, California. The shooting happened around 11 p.m. on Rancho Center Drive at City Ranch Road, a remote, unlit stretch where three men were found dead in the front seats of two vehicles — a Toyota Camry sedan and an Audi SUV. A fourth man survived and was taken to a hospital after calling 911.

Investigators say the attack was set up as a bogus marijuana deal by Jonathan Paul Misirli. Misirli reportedly shot the four men, stole a bag containing about $2,500 in cash and roughly $10,000 in jewelry, and missed a separate container holding about $15,000 in cash. Misirli was later arrested, convicted of three counts of first-degree murder and one count of attempted murder, and found guilty of robbery with special-circumstance allegations; he received life without parole.

Did anyone who knew Olukayode or the other victims have contact with them in Palmdale around mid-January 2019?
