HOUSTON — In a bizarre and disturbing case, Houston police say they’ve arrested a stalker who targeted high-profile Houston socialites and philanthropists, along with former Texas A&M football coach Kevin Sumlin.

The stalker researched his victims thoroughly and even attended their family funerals and weddings, according to investigators.  

Robin Chiswell, 61, is charged with felony stalking in a case involving Carolyn Farb, a fixture on the Houston charity scene for decades.

Farb told police she had been receiving threatening and harassing letters for more than 20 years.

“She feared for her life because, not only did the suspect know where she lived, but he appeared to be following her and the tone of the letters were becoming more aggressive,” an HPD investigator said.

Farb filed several police reports through the years but the letters were sent anonymously with fake return addresses, so it was difficult to track down the sender.

HPD’s Major Offenders Unit recently reopened the case and began working with U.S. postal inspectors.

Their investigation led them to Chiswell and he was arrested in November of 2018.

Detectives searched his home and found “several pieces of evidence, including stationery similar to that sent to Carolyn Farb,” police said.

After interviewing several people who know Chiswell, including family members, police determined there were many other victims.

“Robin Chiswell targeted high-profile socialites and philanthropists known to live in the River Oaks and Tanglewood area,” investigators said.

Along with profanity-laced letters, investigators say Chiswell committed property crimes against people he disliked.

One of the letters was sent to Kevin Sumlin after the Aggies lost a game in 2017.

"You suck as a coach! You're a n****r and can't win! Please get lost! Or else,” the note read.

Police are asking anyone who has received anonymous, threatening letters to come forward. Many of those letters had a return address of the River Oaks Country Club or the Houston Country Club.

If you are a victim in this case or have information, you’re asked to call HPD’s Major Offenders Division at 713-308-3100.
