Bettendorf police spent about four hours on the scene of a situation Tuesday that ended with a woman’s suicide.

The woman was not identified.

Police were called to a home on 23rd Avenue just south of Central Avenue at 3:57 p.m. Tuesday, said Capt. Keith Kimball of the Bettendorf Police Department.

Just after 8 p.m., Kimball confirmed that the woman, who was alone in the house, had committed suicide.

Streets in the immediate area were blocked off during the situation as a precaution, he said. There was a heavy police presence on the scene, including tactical team officers and vehicles.

No other information was released.
