Police arrested a Florida man on first-degree murder charges Tuesday after he allegedly pocket dialed 911 and accidentally revealed his plot to murder another man.

In the phone call recorded on May 5, 24-year-old Scott Simon can reportedly be heard telling someone that he's going to follow another man home and kill him.

Minutes after the call was made, Nicholas Walker, 33, was shot dead while driving onto an I-95 on-ramp. His car hit a guardrail and exploded into flames, shutting down the highway for three hours.

Detectives said they believe Simon was the one to coordinate the killing, but that someone else pulled the trigger that killed Walker. Simon and Walker are said to have gotten into an argument at a Waffle House before the shooting.

Police are currently looking for two other suspects, one of who was seen with Simon in surveillance video earlier that night.
