(Fox News) — The Florida plastic surgeon accused of killing a lawyer from a firm that represented his former employer in a business dispute may have murdered the lawyer in an office bathroom after using a paralyzing agent to subdue him, according to a police report obtained by Fox News Digital.

Dr. Tomasz Roman Kosowski, 44, was arrested and charged with first-degree murder Sunday in the killing of Steven Cozzi, who disappeared from his Largo law office March 21 near Tampa.

Surveillance footage shows a man police believe to be Kosowski pull up in a gray Toyota Tundra at about 8:32 a.m. and enter the building “wearing gloves, carrying a large box and wearing a large backpack,” according to a probable cause affidavit.
