The girl, 17, was caught in the middle of a dispute between her stepfather, Jose Amaro, and his brother-in-law on Saturday night in Deltona, Florida.
Authorities said that after becoming irate, Amaro, 41, shoved his brother-in-law and ran inside his home to grab a handgun. The men were said to have been drinking.
The bullet hit the 17-year-old girl in her right knee, deputies said.
Amaro was said to have been treating her wound before authorities arrived on the scene.
Her step-father was arrested and facing charges of aggravated battery with a deadly weapon, authorities added.
He was given additional charges of possession of ammunition by a convicted felon and two counts of possession of a firearm by a convicted felon after a criminal check was conducted and two New Jersey felony convictions were found.
Many have frowned on President Trump’s response regarding the devastating hurricane that hit Puerto Rico.
Trump came under even more criticism when he irresponsibly chastised San Juan Mayor Carmen Yulín Cruz.
