UPDATE 6 p.m. (KWWL) -- More details have been provided on an armed standoff Friday morning that lasted five hours and ended with the suspect apparently taking his own life.
According to Waterloo Police, officers responding to the Cobblestone Circle Apartments confirmed that shots were being fired.
Officers spent hours attempting to communicate with the suspect using a loudspeaker, honking horns, and turning on the sirens of their police cars. They also knocked out a second-floor window in an effort to talk to the suspect.
Neighbors say at least one shot was fired after police arrived.
After making entry, officers located the body of a man who had died from an apparent self-inflicted gunshot wound in his girlfriend's apartment.
Ansborough Avenue was shut down and several neighboring apartment buildings evacuated as a precaution.
Officers then noticed a concerning package and the Waterloo Bomb Unit was called in. The bomb unit confirmed that the package held no threat to the public.
Police say one person was brought out and taken away by ambulance, but that turned out to be unrelated to the standoff situation.
Cobblestone Apartment Manager Deb Borwig told KWWL's Ron Steele that the shooter was not a tenant of Cobblestone, but had come to the apartment where his girlfriend lives. The girlfriend was attempting to get a no-contact order against the suspect and was not at the apartment.
Borwig says she evacuated 48 apartments as a precaution.
UPDATE 1:30 p.m. (KWWL) -- Incidents at the Cobblestone Circle Apartments in Waterloo have de-escalated following a standoff involving tactical teams and a suspicious package found.
Waterloo Police say that both situations have been resolved.
Police say that a person taken away by ambulance was unrelated to the standoff situation and involved a resident with a medical condition.
Before officers stood down, KWWL reporter Daniel Perreault says that there appeared to potentially be use of smoke bombs.
There is no danger to the public and information about the suspect involved in the standoff will be released by police later.
The apartment complex is no longer blocked off and Ansborough Ave is back open to traffic.
