HOW did a bomb end up in the hands of a 15-year-old Ipswich boy?
That's the question Ipswich magistrate Virginia Sturgess had to consider when the two men charged over a bomb incident, which maimed the teenager, appeared before her yesterday.
Mark Anthony Tear, 38, and Glen Charles Dell, 44, faced a committal hearing to decide if they should stand trial for planting homemade bombs across Ipswich.
It was alleged one of the bombs, shaped like a golf ball, was responsible for the blast that blew off the fingers of the Leichhardt teen in May 2013.
The bomb is believed to have been found in a gutter by teenaged friends of the victim, and they were playing with it when it exploded.
Tear and Dell were charged in July last year after another bomb detonated at the West Ipswich house the pair was renting.
When police investigated, they reportedly uncovered a stockpile of explosives and a bomb-making chemical called Triacetone- Triperoxide - TATP.
Crown prosecutor Noel Needham told Ipswich Magistrates Court evidence found at the men's address linked them to the "golf ball bomb" explosion.
He said the "golf ball bomb" had contained the same TATP substance and all the materials required to build such a bomb were found at the address.
The court heard the explosive was found by the youths at a location which was apparently en-route to Tear's partner's house.
Mr Needham alleged Tear and Dell were also responsible for a homemade bomb that was rigged to a fence at a Bunnings Warehouse construction site in May 2013.
He said the bomb was fashioned out of a party popper, a device Tear had apparently created before. He said the party popper also contained TATP.
Defence lawyer Michael Kelly, who represented Tear, said linking the bombs to the defendants because of substances found in their home was "a leap too far".
He said the construction of the "golf ball bomb" was nothing out of the ordinary and anyone who looked on the internet could learn how to make it.
However, Ms Sturgess said she believed there was sufficient evidence to put both men on trial.
The two men will stand trial at a later date for a series of offences including intent to cause grievous bodily harm and attempting to destroy property by explosives.
