HERNANDO COUNTY, Fla. (WFLA) — Hernando County Sheriff Al Nienhuis unveiled new detail regarding a recent deputy-involved shooting that unfolded in Brooksville on Friday, Feb. 17.

Hernando County deputies were first called to a structure fire at 9139 Erma Road in Brooksville Friday evening. Soon after, authorities learned a man, later identified as 64-year-old Steve Roosa, was opening fire at random residents nearby.

Nienhuis called the incident an “extremely unusual situation because almost never do we have an individual who is shooting at random individuals.”

Deputies tried for hours to negotiate Roosa’s surrender before SWAT team members were ordered to breach the house.

Six minutes after tear gas was deployed, Nienhuis said Roosa exited the home under the porch where he pointed a firearm at authorities.

SWAT team members, in fear for their own safety, shot Roosa, killing him.

Nienhuis said deputies found 12 firearms “staged” throughout the house, including six long rifles, two of which were scoped, two shotguns, three revolvers, and one semi-automatic handgun.

“He was certainly ready for a fight,” Nienhuis said.

One victim later died as a result of their gunshot injuries. Their identity was not released.
