A Grand Teton Lodge Company security guard was hospitalized last week after being attacked and hit over the head with a blunt object – possibly a rock. The unidentified guard was discovered when Grand Teton National Park rangers responded to the report of a loud party at the employee residential area of Jackson Lodge early Thursday morning. Park Spokesperson Jackie Skaggs says the rangers provided emergency medical care to the man and transported him to St. John’s Medical Center. Skaggs says there were several individuals who were at the party and rangers attempted to obtain information from them. However, she says nobody was able to give much information about the assault. Consequently , she says additional agencies have been called in to conduct an investigation into the details of the assault. Crimestoppers has offered a reward of up to $1000 for information leading to the arrest and conviction of whoever was responsible for the attack. Anyone with information about the incident may call the park at 739-3503, or they may contact Crimestoppers – anonymously if they choose – at 733-5148.
