A suspect was shot and killed by Greeley police late Tuesday morning in the Meadow Village Mobile Home Park. Police said a 33-year-old man, armed with a knife, barricaded himself inside a residence on the 100 block of East 20th Street. After three hours, police said the suspect exited the trailer with the knife in his hand, and a Greeley officer filed several rounds, striking him. He was pronounced dead at the scene. No one else was hurt in the incident.
