Witnesses said Musallam works at a restaurant that had just received a passing inspection from Catanyag. CBS13 talked to the owner there who wasn’t ready to do an interview but said as he tried to stop Mussallam and was stabbed himself.

Neighboring businesses locked their doors for safety and said it seemed like Mussallam had snapped for no reason.
