Summary

No credits this week because I didn't want to delay this episode any longer.
For their plan to work, Larry Bittaker knew they couldn’t rely on just any car. They needed something bigger… something that could trap a victim inside. In February of 1979, with money from Norris, he bought it—a silver-gray 1977 GMC Vandura.

The van was windowless on one side, with a sliding door large enough to swallow someone whole. Bittaker later admitted that when he first saw that door, he knew. They could pull up close to a girl, slide it open, and drag her inside without anyone noticing.

The pair gave the vehicle a name. To them, it wasn’t just a van. It was their “Murder Mac.”

buy bags of fast food and bottles of wine, and then hand

him out to the homeless on Skid Row.

Roy Norris walked out of prison as well. He moved back into his mother's home in Redondo Beach,

Weeks later, the two men met at a hotel, old prison acquaintances reunited, and in that meeting,

they breathed new life into a plan they had whispered about behind bars, a plan to stalk,

kidnap, and rape young girls. In Burbank, Norris's hotel room became something of a hangout
