A 56-year-old man, Cesar Sayoc Jr., was arrested Friday morning in Florida in the investigation of 12 suspected mail bombs sent to former President Barack Obama, Hillary Clinton and other leading Democratic critics of President Donald Trump.

Sayoc, a registered Republican voter who lives in Aventura, Florida, will face federal criminal charges for the mailed devices, according to NBC News.

The Brooklyn, New York, native, previously was arrested, in Florida in 2002, on a charge of threatening to throw a bomb. He received probation in that case, without having been convicted.

"I'm as surprised as anybody," said Daniel Lurvey, a Florida criminal defense lawyer who represented Sayoc in several cases in which Sayoc had been charged with theft from retail stores.

At the time, Lurvey said, Sayoc was doing work as a bouncer for a group of male dancers similar to Chippendales.

"He was a normal guy. Somebody I would never think he'd be capable of something like this, if he is responsible," Lurvey said.

The attorney said Sayoc never discussed anything "political" during their meetings about his criminal cases.

Records show that Sayoc also was arrested in 2015 for violating probation in a case in which he first was charged with grand theft and battery.
