(CNN) — An Oregon teen accused of planning to bomb his high school suffers from a rare form of obsessive-compulsive disorder, his family said.
"My heart goes out to everyone affected by Grant's struggle with PANDAS, a rare form of OCD," Grant Acord's mother said through her attorney.
"I grieve for my son, but understand and support the efforts of law enforcement to keep our beloved community safe," the mother, Marianne Fox, added. "This is a challenging and confusing time for everyone who knows Grant. I will have no further comment while I wait with the rest of you to see what unfolds."
