A lone gunman killed four people and wounded three more -- including a police officer -- on Monday after opening fire in multiple locations across Colorado before being shot dead, US police said.

The incidents began at around 5pm and unfolded across at least four different locations in the cities of Denver and Lakewood, police said at a late night press conference.

Two adult women were killed and an adult male wounded in the first location in Denver, police said, with a further man shot dead.

The gunman then traveled to neighboring Lakewood where he fatally shot another man and wounded another individual.
