The family of Boden Umpherville says he is clinging to life after being stunned and seriously injured following a vehicle stop by police in Prince Albert, Sask., last weekend. The Indigenous went into medical distress shortly after the arrest, police say. He was sent to hospital in serious condition. The province's new police oversight agency said multiple police officers used their stun guns, batons and pepper spray during the "altercation." The agency found a loaded handgun at the scene.
