DENVER — Police are looking to identify four people who are wanted for robbing at least five marijuana dispensaries in three different cities.

According to Denver Police, the first hold-up happened Nov. 4 at A Cut Above located in the 1900 block of S. Broadway in Denver.

On Nov. 19, the group hit Green Heart Dispensary on East Quincy Avenue in Aurora. That is where 24-year old Travis Mason was shot and killed in June 2016 while working as a security guard.

In all of the robberies, the four suspects wore dark hooded jackets and masks to hide their faces. They were armed with multiple weapons, according to police.
