The Martin County Sheriff’s Office said in a Facebook post on Sunday that it has stopped the vehicle on northbound Interstate 95 and taken a suspect into custody who is believed to be connected to the shooting.
The sheriff’s office said it made the stop after authorities in neighboring Palm Beach County put out a “be on the lookout” alert.
Sheriff William Snyder told WPTV that the suspect “was not armed when we took him out of the car.”
The man had a calm, flat demeanor and showed little emotion when he was stopped by police, Snyder said, saying the suspect did not question why he was being pulled over.
“He never asked, ‘what is this about?’ Obviously, law enforcement with long rifles, blue lights, a lot going on. He never questioned it,” Snyder said.
Attorney General Merrick Garland has been briefed on the situation and is receiving regular updates about it, a Justice Department spokeswoman said.
The post by the Martin County Sheriff’s Office indicated the suspect was apprehended near Palm City, Florida, about a 45-mile drive north of Trump’s golf course. Northbound lanes of I-95 were shut down, the sheriff’s office said.
A message sent to campaign officials seeking information on the security status and location of Ohio Sen. JD Vance, Trump’s running mate, was not immediately returned.
Max Egusquiza, of Palm Beach, described the emergency response outside Trump’s West Palm Beach golf course.
“From what I saw 5 black unmarked SUVs blocked in a grey Mercedes in front of the golf course. There were about 20 or more cop cars flying from nearby streets,” he said.
