US supermarket shooting suspect got assault weapon 6 days before shooting

The suspect purchased the gun just six days before the shooting inside a crowded Colorado supermarket in the US, according to the arrest affidavit.

US Police on Tuesday identified a 21-year-old man as the suspect who opened fire inside a crowded Colorado supermarket, and court documents showed that he purchased an assault rifle less than a week before the attack that killed 10 people, including a police officer. Supermarket employees told investigators that Ahmad Al Aliwi Alissa shot an elderly man multiple times Monday outside the Boulder grocery store before going inside, according to the documents. Another person was found shot in a vehicle next to a car registered to suspect's brother. Authorities said Alissa was from the Denver suburb of Arvada and he engaged in a shootout with police inside the store. The suspect was being treated at a hospital and was expected to be booked into the county jail later in the day on murder charges.
