The family members of a missing 20-year-old Missouri college student are now offering a ten-thousand dollar reward for tips leading to his return.
Ross is from Belton.
His family was initially offering a five-thousand dollar reward but say the announcement hasn't generated much of a response.
His father Don Ross says the family's goal is to bring the 20-year-old home safely.
Police divers have used sonar to search the waters around the Michigan Avenue Bridge where Ross was last seen.
