The Wah Mee massacre occurred in Seattle on February 19, 1983, when a robbery at a private gambling club in the Chinatown-International District ended with thirteen people dead. Three perpetrators—Kwan Fai Willie Mak, Benjamin Ng, and Wai Chiu Tony Ng—were identified and later convicted after trials that relied heavily on the testimony of the lone survivor.

The available archives and reports from the period do not include information about a man by that name dying under those circumstances.

Does anyone have documentation or personal knowledge that connects Jack Mar to Seattle on February 19, 1983?
