On the evening of March 29, 2025, 21-year-old Landen Roggenkamp was shot inside a residence in the 1400 block of East Mart-Way Circle in Olathe, Kansas. Roggenkamp and a 25-year-old man, Armando Javier Guerrero, had been drinking heavily; an altercation between them led to Roggenkamp making a Snapchat video call pleading for help before the shooting. Officers who responded just before 10 p.m. found Roggenkamp inside with multiple gunshot wounds; he was transported to a hospital and later pronounced dead.

A witness who had received a second call for help arrived to find Guerrero leaving the scene and Roggenkamp inside the bedroom. Guerrero fled on foot but was encountered by police during a perimeter search and taken into custody; officers noted what appeared to be blood on his clothing. The investigation was treated as a homicide.

Who knew Landen or was at the residence that night and can provide details about what happened before the shooting?
