(Associated Press) The man police say opened fire with a gun from his checked baggage at a Florida airport had a history of mental health issues — some of which followed his military service in Iraq — and was receiving psychological treatment at his home in Alaska, his relatives said Friday after the deadly shooting.

“Only thing I could tell you was when he came out of Iraq, he wasn’t feeling too good,” his uncle, Hernan Rivera, told The Record newspaper (http://bit.ly/2j04ghF ).

Esteban Santiago, 26, deployed in 2010 as part of the Puerto Rico National Guard, spending a year with an engineering battalion, according to Guard spokesman Maj. Paul Dahlen.
