Beeler's daughter, Lisa Wallen, said doctors are "unsure what is medically wrong" with her father at this time.
On the way to Terre Haute Regional Hospital, Wallen said her father is feeling downhearted at the possibility of missing his 61st year as Santa Claus and appearing as Santa during the Christmas In The Park Parade.
Several community members contacted The Brazil Times Friday, wanting to know how to cheer up their favorite jolly old elf.
According to officials at Terre Haute Regional Hospital, cards and letters can be sent to Beeler in care of the hospital's address:
