(CNN) Five law enforcement officers were shot and one of them died after a barricaded suspect opened fire at an apartment complex in a Denver suburb, the Douglas County Sheriff said Sunday.

Two civilians also were shot and the suspect was shot and killed later by police, Sheriff Tony Spurlock said.

The sheriff said Deputy Zackari Parrish, 29, was killed. The four injured officers are in stable condition, Spurlock told reporters.

"This is a tragic day that we will be feeling for a long time," Spurlock said. "Zack was a good kid, smiley kid. He was eager to work, eager to serve."
