I'd like to know how a 17 year old got ahold of a pistol.

Maryland generally prohibits any person under age 21 from
possessing any “regulated firearm” (handgun or assault weapon).
Maryland also prohibits any person from
transferring a regulated firearm to a transferee who the person knows or has reasonable cause to believe is under 21 years of age.
Maryland also prohibits any person from
selling, renting or transferring ammunition for a regulated firearm to a person under age 21, or any ammunition to a person under age 18.
Maryland also
prohibits the sale or transfer of a rifle or shotgun to a person under age 18.
However, there appears to be
no minimum age to possess a rifle or shotgun in the state.[/b]
There laws are close to Hawaii's.
See the "un-biased"

description below.

"Even with such strict restrictions on guns, Maryland routinely ranks among the most dangerous states in terms of violent crime statistics.
One in every 156 citizens is the victim of a violent crime, while
one in 11,427 is murdered. These bleak numbers can be mainly attributed to Baltimore's struggles and failure to revitalize.
Numbers may be misleading given the presence of dangerous urban landscapes. 
Although unpleasant, one can only imagine how the statistics would look if Maryland gun laws were mitigated."
