A Matteson man wanted on explosives charges turned himself Thursday and is being held on a $100,000 bond.
Michael Dorosz, 19, surrendered at the Markham courthouse after a warrant was issued for his arrest last week. He’s been charged with one count of unlawful use of a weapon in connection with the hundreds of pounds of fireworks and explosive chemicals authorities said they found in his trailer.
Cook County Sheriff Tom Dart said enough explosive material was found to level a city block.
"This would have been horrific damage, horrific casualties if this had [exploded]," he said last week.
Dorosz's 21-year-old sister, Felicia West, has also been charged in the case. Police said they found West, her five-year-old daughter and a locked-up dog in a trailer with the explosives.
The materials are believed to have been collected to make homemade fireworks and were found when police responded to a reported burglary.
Police destroyed the material in 81 separate explosions in a quarry on June 11.
Dorosz was arrested for possession of fireworks for a separate incident in May, pled guilty and was fined $250, police said.
The pair's next court date is July 1 in Markham.
