MENOMONIE, Wis. (WTAQ) - The State Crime Lab said the same gun was used to kill 4 relatives and wound another at a family gathering at a mobile home park in Menomonie last summer. The state’s report agreed with Menomonie police investigators. They said 23-year-old Geu Tou Vang shot and killed 3 brothers and a cousin before taking his own life. And officials say there’s no evidence the shootings were premeditated or gang-related. The shootings apparently stemmed from an argument about a missing bottle of alcohol.
