The victims were found about 4:45 p.m. Monday at a house on a tree-lined street in the northeast Kansas community.
A news release from the police department calls the case a homicide investigation but says it's not known how the four died. Calls to the department Monday night were not immediately returned.
Names were being withheld while relatives were notified. Several blocks around the house were closed off.
