A judge told 19-year-old Taveuan Williams and 23-year-old Michael Annan they were being investigated for three felony charges. The charges include attempted first degree murder of a police officer, kidnapping and aggravated robbery.
A bond for both suspects was set at $200,000.
The six-hour standoff at a Denver RadioShack store ended peacefully Friday afternoon when Williams and Annan released their hostage and walked out of the store around 3:45 p.m.
The hostage was identified as 28-year-old Chris Nimerfroh, the store's manager.
Police responded to the RadioShack at 5305 East Colfax Friday morning after a report of a robbery.
Police arrived before Williams and Annon were able to get away. One of the suspects was attempting to leave, but ran back inside when police showed up and took Nimerfroh hostage.
The suspects shot several rounds, but police say no one was hit.
Police entered the store and conducted negotiations as a SWAT team surrounded the building.
9Wants to Know has learned friends and family were reaching out to Taveuan Williams during the standoff through Facebook.
A woman named Charisma posted on his timeline:
"Man, cousin please surrender I love u and I'm praying for you."
Strangers even tried engaging Williams. A woman named Arlene in Wichita left the following message:
"I don't live in Colorado, but I just wanted to tell you people really care, they really do. If you would just come out and give them a chance to show you, then it would be ok."
Records show Williams plead guilty to felony vehicle theft only four days after his 18th birthday. A month later, he plead guilty to the first of several theft and larceny charges. He was charged with identity theft and forgery in February 2012.
Details of Annan's record were not immediately available.
