Maldonado said she won't let her 7-year-old son play in the yard.
"We don't open the door or nothing. A lot of people are scared. I'm scared for my son, for the neighborhood," she said.
Seminole Heights is a working-class neighborhood northeast of downtown Tampa that's slowly becoming gentrified. Run-down homes sit next to renovated, historic bungalows, and trendy restaurants have sprung up near auto body shops.
Residents and business owners said there are car burglaries and fights between children, but they are not accustomed to anything like the violence that started Oct. 9.
"We don't know what's next," said Majed Foqahaa, owner of the M&M market.
He said two of the victims would come into the store and buy soda and snacks. Foqahaa said he has a concealed carry permit for a handgun, and he keeps it at the store while he is working. When he walks out to his car at night, he holds it in his hand.
Tampa Mayor Bob Buckhorn said the city has put dozens of officers in the area around the clock. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives also are helping, he said.
"There aren't a lot of facts, or evidence, yet," Buckhorn said as he visited a block where one victim was killed. "But it's not for lack of Tampa Police Department trying. We literally have put bodies out here by the dozens. We're going to find this guy and we're not leaving this neighborhood till we do."
"We can call it what we want, if that brings attention to this. That's fine," Dugan said.
Lula Mae Lewis, an 80-year-old woman who has lived in the area for 30 years, lives across the street from where Hoffa's body was found.
"I heard the shots that Wednesday night," she said. "But I was afraid to open my door because they were so loud, it sounded like it was just right here."
