Cops: Gunman dead after shooting woman in downtown Denver

DENVER -- Denver Police swarmed an area near an office building in the city's LoDo, or lower downtown, neighborhood Tuesday afternoon after they say a gunman shot a woman and then took his own life.

The incident was reported around 2:45 p.m., reports CBS Denver. Police tweeted at 3:17 p.m. that they were clearing the building, known as the Alliance Center. Around 3:40 p.m., they tweeted that the scene was secure.

Police say they believe the shooting was targeted and that the suspect and victim knew each other. One victim, a woman, suffered multiple gunshot wounds and was in critical condition. When police responded to the victim, they said the suspected gunman was already dead.

Jake Williams, executive director of Healthier Colorado, which has offices in the building, told Crimesider he was on the third floor of the building when he heard a woman screaming and felt a "rumbling" on the floor beneath him.

"I heard a sound I believe to be a gunshot and we could smell gunpowder," Williams said.

Williams said he believed the shooting happened on the second floor.

Williams said the building housed a number of nonprofits, many sustainability-focused. He estimated there were about 100 people in the building.

Video posted to Twitter by Erica Cano showed people running out of a building with their hands up.
