Matthew Christensen was 19 when he left his Buckeye, Arizona, home on the evening of Tuesday, April 28, 2015, saying he was giving a friend a ride. When he did not return, his family reported him missing. The next morning a walker found a body on a neighborhood path near 236th Lane and Hilton Avenue, behind Inca Elementary School; the deceased was later identified as Matthew and had been shot multiple times.

Buckeye Police investigators followed tips from the public that led them to two local men, 18-year-old Richard Burns and 21-year-old Zackary Howard, who were arrested on April 30. Both admitted involvement and said they had conspired to rob Matthew at the walking path; during the robbery he was shot and the suspects fled in his car. Burns and Howard were booked on charges including first-degree murder and aggravated armed robbery, and the case proceeded through the courts.

Does anyone have information about Matthew’s last known movements or about the walking path area near 236th Lane and Hilton Avenue?
