A 36-year-old man was charged Monday in Kitsap County Superior Court with stabbing a man his wife had gone on a date with, leaving the victim with multiple stab wounds to his back.

Masson Warwick Manson allegedly attacked the man, described in court documents as his wife’s boyfriend, when the couple returned from a date to a residence on Naval Base Kitsap-Bangor early Sunday morning.

The boyfriend was in the passenger seat of the woman’s vehicle when Manson opened the car door and attacked him, according to court documents.

After a “brief struggle” between the husband and wife, the woman disarmed Manson.

All three were taken to Harrison Medical Center in Bremerton with knife wounds.

Manson was charged with first-degree assault for the attack on the man and second-degree assault for the wounds sustained by his wife.

Manson is a civilian, said Kitsap County Sheriff's Deputy Scott Wilson.
