MADISON, Wis. (AP) — Gov. Scott Walker has ordered that flags at state buildings be flown at half-staff to honor a fallen Wisconsin Marine who was killed at his base in California earlier this month.

The order honors Ethan Barclay-Weberpal who was killed Jan. 16 at Camp Pendleton. Officials say another Marine was taken into custody but haven’t provided many details on the investigation.

Barclay-Weberpal is from Janesville and attended Parker High School before transferring to an out-of-state school in November 2015.

Flags should be flown at half staff Monday, Jan. 29 from sunrise to sunset.
