Although Jerohm lived and hung out mostly in the Bay View district between Hunter's Point and Candlestick Park – one of the coldest and most inhospitable environments in the state – at about midnight on June 21-22 he was arrested by an African-American inspector sergeant of homicide named Ridley Banks as he exited the Kit Kat Klub just north of Laguna, a long walk from Candlestick, after his presence had been reported by that establishment's owner, Mo-Mo House, who had some sort of arrangement with Sergeant Banks. Accustomed to the drill, Jerohm offered no resistance.

A search of Jerohm's given address, an apartment he shared with an eighteen-year-old unemployed hairdresser named Carryl Joyner and her two-year-old Damien, turned up one of Michael Mullen's credit cards.

Jerohm professed ignorance as to how the credit card had come to rest between the cushions of his couch, saying that maybe it had fallen out of the pocket of his friend, Tooth, when he'd been visiting. Tooth, sadly, had died a few days ago when he had gotten hold of some extra pure Mexican brown heroin and mixed up a speedball with it. That's how Jerohm's fingerprint must have gotten onto the steering wheel, said Jerohm. Thinking it had been Tooth's car, Jerohm had had to drive Tooth home in it that night – the man was really messed up and his woman would kill him if he spent the night out again. Jerohm hadn't noticed the blood – it must have been on the seat or something, got transferred to his finger.

Two days after Jerohm's arrest, a Friday, he took part in four separate police line-ups. On the good side of the glass, on these four occasions, respectively, sat Josh Cane, who had been the driver behind Michael Mullen; Rayanne Jonas, the day-care provider; Luis Santillo, still in a cast with a bandage wrapped around his head; and Riley Willson of Riley's Garage.
