An investigation continues involving a Troy man who went missing.

Authorities say 49-year-old Michael McMahon was involved in a domestic incident not long before he went missing. A police report from last month says McMahon was assaulted with a knife.

The suspect in that case, 27-year-old Salina Brown-Shook, was arrested at the time and faces several charges, including assault and strangulation.

If you have any information regarding McMahon's disappearance, you're asked to call Troy Police immediately.
