A Carmel man has been arrested for promoting an obscene sexual performance by a child.  The Putnam County Sheriff's Office received a referral from law enforcement in Texas about 44-year old Brian Lockhart sharing Child Sexual Abuse Material through a chat program. After a joint investigation, Lockhart was charged on September 17th.  K9 Hannah, the Sheriff Department’s electronics detection dog, assisted in the execution of the search warrant that resulted in the recovery of over a dozen electronic devices.  Multiple devices were seized at his home and the digital forensics examination process is still ongoing. Investigators advise that there may be more charges or investigations initiated at the conclusion of the digital forensics exam.  The Putnam County Sheriff's Office is part of the Internet Crimes Against Children Task Force run by New York State Police.
