Boston Municipal Court Judge Thomas Horgan ruled today that Kevin "Kayvon" Edson is competent enough to assist in his own trial, following a mental-health evaluation at Bridgewater State Hospitals, the Suffolk County District Attorney's office reports.

Edson is charged with disturbing the peace, disorderly conduct, disturbing a public assembly, possession or use of a hoax device and making a false bomb threat for an incident April 15, not long after memorial services at the Boston Marathon finish line.
