A federal judge will decide whether a man accused of setting off a small explosion near a Colorado NAACP office should stay jailed before his trial.

A detention hearing is set for Wednesday for 44-year-old Thaddeus Murphy, who was charged with arson of a building and being a felon in possession of a firearm after the Jan. 6 blast. Investigators say Murphy told them he was distraught about his financial problems and was actually targeting his accountant.

They say he admitted to making a pipe bomb in his garage and setting it off because he was mad the accountant did not return his phone calls or give him back his tax records. It is unclear whether Murphy knew the accountant died in June.

Authorities initially investigated the blast as a potential hate crime.
