Dozens of people gathered outside a Logan apartment to honor two young people, one of them from Idaho Falls, killed there in a murder-suicide earlier this week.

Relatives joined Utah State University students and Logan police at a candlelight vigil Tuesday night in memory of 19-year-old Mackenzie Madden and 25-year-old Johnathon Sadler.

Authorities say 23-year-old Army National Guardsman Jared Tolman kicked down the door of Madden's apartment early Monday morning and shot the two dead.

Police say Tolman fatally shot himself later at another home.

Sadler's mother told the Logan Herald-Journal that her son and Madden had gone on their first date that night, and Sadler stayed with her to protect her after she received frightening text messages from Tolman.

Madden was a sociology student at USU from Idaho Falls, while Sadler was a manager at a construction company.
