OAKLAND PARK, Fla. – The Broward Sheriff's Office arrested a 24-year-old man accused of mentioning a murder on a recorded line after he accidentally called 911.

BSO charged Scott Simon with first-degree murder on Tuesday.

On May 5, Simon pocket dialed 911, and while the call was being recorded, told someone he was going to follow the victim home and kill him, according to investigators. Minutes later, 33-year-old Nicholas Walker was shot and killed while driving his car on Interstate 95.

Investigators believe Simon coordinated the shooting after getting into an argument with Walker at a nearby Waffle House.

Investigators released surveillance video of another man, wearing a sleeveless, studded denim shirt (pictured below), believed to be involved in the shooting. He and a third man were in a black 2012 Buick GS in the early-morning hours of May 5.

Anyone with information on the shooting is asked to call Broward Crime Stoppers at 954-493-TIPS.
