SMITH COUNTY, Texas — The Smith County Sheriff's Office arrested a man suspected of dealing LSD and other drugs in the county.

According to the SCSO, undercover investigators were watching a home in the southern part of the county. During their surveillance, the investigators saw 19-year-old Logan Carr, who is a suspected drug trafficker, leave the home and drive to a business in the 12400 block of Highway 155 South in Tyler.
