(Amity, OR)  --  Few details are being released about the shutdown of Highway 99 in Amity.  Police say the highway was closed off for several hours yesterday, due to an investigation of threats and assaults against a family living there.  Authorities say they received a report of a man approaching somebody in the family and attempting to grab them, and that the suspect was badly injured and fled.  Police say the suspect, described as a short Hispanic man with a dragon tattoo on his left forearm, got in a red or maroon SUV with a man and a white female and drove off.
