PUEBLO, Colo. -

Police say the man who opened fire in a Pueblo bar, killing a man and an unborn baby, knew at least one of the victims.

Damen Blake, 37, is accused of killing Quincey Coates. Police say Blake also shot a pregnant woman. While she survived, her baby was delivered and later died.

According to the arrest affidavit for Blake, when police asked the woman who would want to hurt Coates, she immediately named Blake.  

Blake and Coates have a history of violent arguments.  

In May 2012, Coates was suspected of menacing with a deadly weapon outside of Blake's car.  In May 2014, Blake was shot several times in the chest while sitting in his car.  While police never arrested Coates, the affidavit shows the suspect vehicle description is similar to the vehicle driven by Coates.

The surveillance system at Sharky's Bar captured the the events leading up to the shooting, including a man wearing a hoodie and mask walking into the bar and shooting Coates numerous times.  Witnesses and Facebook photos led police to believe the shooter was Blake.

Blake used to live with Sharky's bar employee Michael Rodriguez.

"I met Damen (Blake) here. We used to be friends. He was a good guy. I had no problems with him," said Rodriguez.

Rodriguez said Blake has been struggling since he was shot and going through an "unpeaceful" time.

"I don't know what escalated that high to make him act like that, but he is not that kind of person. He is a good person. Had to be something pretty bad for him to get cared away. He went to the extreme.  Unfortunately, other people had to pay the price.  It's sad," said Rodriguez.

Rodriguez does not know why the two men did not get along.  He said Blake did not cooperate with police when he was shot because he most likely wanted to handle the situation on his own.

"I have no idea what could make them go to that extreme," said Rodriguez.  "It must have been something pretty good. You don't shoot someone over $40."

Rodriguez believes Blake targeted Coats and the pregnant woman was an innocent bystander.

"It's unfortunate things like this happen and you know people get hurt, innocent bystanders," said Rodriguez.

Blake faces two counts of first-degree murder.
