(CBS) — Two people are dead after Glenwood police responded to a call from a man who claimed to have killed his wife and son, authorities said.

When officers showed up at a home near 194th and Minerva around 3:30 p.m. they found a man with self-inflicted injuries. Inside, they found two people dead — a female and a male — Glenwood Police Chief Demitrous Cook tells CBS 2.

Paramedics transported the injured man to a nearby hospital.

Police were waiting on a search warrant to begin their investigation, Cook says.

Illinois State Police are assisting.
