The shooting occurred Sunday at a video game tournament at a shopping and dining complex in downtown Jacksonville, Florida.  According to the sheriff's office, there are 13 victims total -- 11 with gunshot wounds, two with other injuries and the dead suspect. Three people were killed.

"The single suspect in this case is a white male. And this is pending confirmation but we believe the suspect to be 24-year-Old David Katz from Baltimore, Maryland. And the FBI is assisting us with that leg of the investigation in Baltimore," said Sheriff Mike Williams.

Those FBI and ATF agents were heavily armed... and could be seen escorting an unidentified man and woman into a home.

"Pray for Jacksonville as we deal with this senseless tragedy." said the city's mayor Lenny Curry.
