The Colorado Bureau of Investigation (CBI) is seeing a decrease in the number of background checks and gun sales in 2019, according to a news report. 

Between 2017 and 2018, background check approvals were down more than 5 percent, the report says. In the first four months of 2019, there have been more than 112,000 such background check approvals and for all of 2018, there were more than 340,000 checks. Just in April, the Colorado Bureau of Investigation reported more than 14,000 background check approvals for handgun or long gun sales.

CBI reports that background checks have fallen by 10 percent so far in 2019, which means 13,000 fewer guns sold than in 2018. 

A graph, accompanied by the report, shows that gun sales tend to rise when active shooter events such as the Sandy Hook, Pulse Orlando, San Bernardino and the Parkland mass shootings take place. 

In April, among the reasons why people failed their background checks and were denied permits were history of sexual assault, robbery, assault, burglary, larceny or possession of dangerous drugs.
