Topeka ? A Topeka man was declared dead after being pulled from a tributary of the Kansas River.

Emergency responders called to the area by friends of the man Wednesday evening tried to revive him, but he was pronounced dead at the scene near a treatment plant on Topeka’s northeast side.

Shawnee County deputies do not suspect foul play, adding that the man’s relatives said he had a history of seizures. As of late Wednesday, investigators did not know what caused the man to go into the water.
