The victims were identified by family as Randy Reimer, 74, and Susie Reimer, 70, FOX station WITI reported, citing family members. The husband and wife, who celebrated their 50th anniversary in June, had been traveling for a wedding in Wisconsin and were on their way home when the crash occurred, according to the outlet. The couple's son told ABC affiliate WISN that his father, who piloted the aircraft, had a passion for flying — and built the plane himself. "He spent three and a half years building that," Matthew Reimer told the outlet. "It was his pride and joy." "When they retired from living in Menomonee Falls and moved out to Albuquerque, first thing he did was move by the kids so he could build his own airplane," he added. The Waukesha County Sheriff's Office was notified at 9:41 a.m. on Tuesday "that the FAA Terminal Radar Approach Control (TRACON) at Milwaukee lost both radio and radar communication with an airplane," according to a news release. Around the same time, the Waukesha County Communications Center "received phone calls from citizens in both the Village of Vernon and Village of Waukesha reporting a loud noise and possible debris in the area," officials said.
