Beaumont police and federal officials are investigating an explosion that damaged St. Stephen's Episcopal Church when a package detonated late Wednesday night or early Thursday morning - the second time in one month that an explosive device has been found in Beaumont. BPD Chief Jim Singletary declined to comment on the contents of the device or a possible motive. Singletary said Beaumont police responded to a call to the Delaware Street church at 9:18 a.m. Thursday. When officers arrived, they found a package that had already detonated, he said. The Episcopal Diocese of Texas said in a statement Thursday afternoon that the blast "broke out windows, put holes in the office walls and blew apart the bushes lining the entrance."
