Alexis Martin-Collins, 31, was killed in Harlan, Iowa on March 6, 2025. A licensed practical nurse and mother of four, she was described by family as vibrant, outgoing and adventurous. Deputies from the Shelby County Sheriff’s Office responded to a welfare check at a Harlan residence where they encountered 36-year-old David Plagman armed, which led to a standoff.

During the confrontation Plagman made aggressive movements toward deputies and was shot; he was taken to a local hospital and died. After the standoff, officers entered the home and found Alexis Martin-Collins’ body. Investigators later confirmed she had been killed by Plagman before deputies arrived. The deputy involved was placed on administrative leave pending an investigation.

If anyone knew Alexis, her family, or the nature of her relationship with Plagman, or has information about the events that night, please share what you know.
