FORT PIERCE, Fla. (AP) - As early as third grade, the Florida nightclub shooter talked frequently about sex and violence and before finishing high school was suspended for a total of 48 days, including for fighting and hurting classmates, school records showed. In the years since, other people reported having disturbing run-ins with Omar Mateen, including a bartender who said he stalked her nearly a decade ago and sent so many uncomfortable Facebook messages that she blocked him on the social network. Mateen, whose attack on the Pulse nightclub left 49 people dead and 53 wounded, enrolled in Florida public schools after his parents moved in 1991 from New York City to Port Saint Lucie, on the Atlantic coast.
