MONTGOMERY, Ala. (WIAT) — The Alabama Law Enforcement Agency has arrested a suspect in connection to suspicious letters that were delivered to government officials.

Special agents assigned to ALEA’s State Bureau of Investigation responded to the Alabama State House at around 9:15 a.m. Wednesday to investigate three letters that were addressed to members of the Alabama House of Representatives. According to ALEA, each letter contained pornographic images. A fourth letter was sent to Governor Kay Ivey’s office.

ALEA special agents immediately identified a person of interest in their investigation.

Watson is a former Driver License Examiner assigned to ALEA’s Driver License Division. He was placed on mandatory leave on Wednesday, but he resigned on Thursday in lieu of termination.
