(COLORADO SPRINGS) — The Colorado Springs Police Department (CSPD) has arrested a man in connection to an explosion in Downtown Colorado Springs earlier in January, and said he is possibly a suspect in other explosions.

According to CSPD, 69-year-old Edward Kiley was arrested on Jan. 23 in connection to an explosion the evening of Jan. 12 in the 500 block of East Costilla Street, west of Downtown. CSPD said when officers arrived on the scene the night of the explosion, they found several items that indicated an improvised explosive device had been used.

CSPD said the Regional Explosives Unit (REU) responded to assume the investigation. After obtaining a search warrant on Jan. 19, the REU searched a home in the 700 block of East Vermijo Avenue.

As a result of the investigation, Kiley was arrested on Jan. 23 without incident.

This is not the first time Kiley has been arrested in connection to an explosion; in 2018, FOX21 News reported that Kiley had pleaded guilty in connection to an explosion in February of that year, and was sentenced to six years in prison.

CSPD said it has reason to believe that Kiley is potentially involved in other explosions, and is asking the public for help. If you have any information that can assist in the investigation of Kiley, you are urged to contact CSPD’s non-emergency line at (719) 444-7000.
