Wearing a surgical-type mask, he pointed a small silver pistol at the store employee, demanded money and threatened to shoot the employee. After the employee was unable to open the cash register quickly, Rosario Lopez fired one round in the direction of employee and then fled. The employee was not struck by the projectile.
On March 26, 2020, Rosario Lopez entered the Citgo Gas Station located at 788 West Main Street in New Britain. Wearing a surgical-type mask, he waited for another customer to leave the store, approached the counter, pointed a small silver pistol at the store employee and demanded money.
