More on Katz, the Jacksonville shooter:

Lots of vids and pics.

"On Sunday night, FBI and ATF agents raided a home in the upscale Federal Hill neighborhood of South Baltimore.

It is believed to be the home of Katz's father, where the shooter himself also lived.

The agents could be seen inside the home Sunday evening near Baltimore's Inner Harbor.

Says Dad worked for NASA, Mom worked for USFDA.

There is a Chicago Pizza in the Fla. complex, and the Jacksonville Landing complex is on the

St. John's River.

Hope it's not a dupe, but has location info to zero in on the parents.
