“We’d had so much fun, we were jumping around,” he said. There were character actors in a courtyard space near the escape game building and carnival games where the group was standing.

Yochim’s group started laughing and joking with someone they thought was a cast member. At one point, he handed Yochim’s friend a knife and told her to stab him with it, as retribution for a teasing joke.

“Keep in mind, we’d been chased by chainsaws, holding other weapons, all kinds of stuff all night, and it was all fake,” he said. “So she stabs at me with it, and everything got really black.”

When Yochim looked down, he saw blood pouring from a knife wound that went clear through his forearm.
