This is really strange. There were gunmen in two different locations but there appears to be a link between the killings:

A gunman shot four staff members at a missionary training center near Denver early Sunday, killing two, after being told he couldn’t spend the night. About 12 hours later and 65 miles away, a gunman fatally shot a parishioner at a megachurch and wounded four other people before a guard killed him, police said.
The police chief in Arvada, a suburb about 15 miles west of Denver where the mission workers were shot, said the shootings may be related to those at the Colorado Springs church but declined to elaborate. Arvada authorities said no one had been captured in the shootings there.
The gunman at the New Life Church in Colorado Springs was shot and killed by a church security guard after entering the church’s main foyer with high-powered rifle shortly before 1 p.m. and opening fire, Colorado Springs Police Chief Richard Myers said. Four others were wounded, Myers said.
The church’s 11 a.m. service had recently ended, and hundreds of people were milling about when the gunman opened fire. Nearby were parents picking up their children from the nursery.
Police arrived to find that the gunman had been killed by a member of the church’s armed security staff, Myers said.

The mission training program in Arvada has a small office at the church’s World Prayer Center on the New Life campus.
About 7,000 people were on the Colorado Springs campus at the time of the shooting, Boyd said. Security at the church had been beefed up after the early morning shootings in Arvada, he said.

Arvada Police Chief Bob Wick, asked whether he believed there was reason to think the shootings are related, responded, “Yes, there is reason to believe that.”

Thank the Lord that more people weren’t killed!
