That’s exactly what happened to one Florida man on Tuesday morning at his home in the Cumberland Apartments in Orlando.

As he was receiving treatment, hooked up to a dialysis machine inside his apartment, he saw a young man cut open a screen door and entered his patio.

“That’s why I pulled the gun and tapped the window to let him know, I’ve got a gun. And then he took the advice and jumped back over the rail and got out of there,” the homeowner explained.

24-year-old Jonathan Herd was later arrested and faces burglary charges.
