MIAMI – A South Florida man has been sentenced to 15 years in prison for posting bomb-making instructions on the internet for people who he believed were Islamic terrorists.

Court records show that 29-year-old Samuel Baptiste was sentenced Wednesday in Miami federal court.

He pleaded guilty in October to attempting to provide material support to terrorists.

According to an indictment, Baptiste posted documents online in November 2016 that included “Instructions: How to Make a Homemade Pipe Bomb,” “Pipe Bombs,” “Improvised Explosive Devices” and “Improvised Munitions Black Book, Volume 1.”  

Prosecutors say Baptiste posted the information for people who he believed were acting on behalf of the Islamic State terrorist group.
