At least 12 police officers and detectives were at the scene of the shooting within minutes of receiving the call, according to WIBW News. Kansas Highway Patrol troopers were also called in to help take statements and to block off a portion of the road.

Both the shooter and all of the victims were linked with the home but Stuart did not reveal their specific associations.

Staff members and residents were taken out of the home as part of the investigation.

The victims were identified as 64-year-old Jesus Galvez, 29-year-old Larry Gueary, and 20-year-old Soren Galvez.

Joshua Gueary, 25, was identified as the gunman.
