A welfare check at a Marshalltown, Iowa, home in the early hours of April 19, 2024, uncovered two bodies. Thirty-three-year-old Frances Tillie Gasca and 28-year-old Mario Murillo were both pronounced dead at the scene, and investigators treated the incident as a double homicide.

Frances Gasca was a native of Lompoc, California, who had moved to Iowa years earlier. Her sister described her as a loving mother to four children and remembered her as vibrant and talkative. Authorities identified 29-year-old Ilias Lasley as a suspect and pursued him as armed and dangerous; he was taken into custody in Des Moines on April 20, 2024, and charged with two counts of first-degree murder.

Prosecutors have said a possible motive is that Lasley became upset after Gasca and Murillo were speaking Spanish before he shot them. Lasley has pleaded not guilty and the trial has been delayed. If anyone knew Frances, Mario, or was in the Marshalltown area that night, please share what might help the investigation.
