Four people have been found dead following a shooting incident that triggered a stand-off with police in Aurora, Colorado.
Police said that they went to a townhouse after shots were heard there overnight.
Police said that following a gunfight they found the suspect dead, along with three people apparently killed earlier, the BBC reports.
Aurora, near Denver, was the scene of a mass shooting at a cinema in July, in which a gunman killed 12 people.
He opened fire at random during the premiere of the Batman film The Dark Knight Rises. Suspect James Eagan Holmes is currently being tried on murder charges.
In Saturday's incident, police said they were alerted by a woman who had escaped from the townhouse.
The suspect barricaded himself for five hours, before officers moved in and shot him.
After entering the house, police found the shooter dead, along with two other men and a woman, the report added. (ANI)
