Days after Texas A&M’s loss to UCLA in 2017, then-head coach Kevin Sumlin received a letter with a racial slur that said “please get lost” followed by “or else.” The man behind that letter has been identified by authorities.

Brent Zwerneman of the Houston Chronicle reported this week that Houston resident Robin Chiswell has been identified as the person who wrote the letter to Sumlin. Zwerneman’s Thursday article noted that Chiswell was scheduled to be arraigned in Harris County (Houston area) on Friday. Brazos County (College Station) authorities were said to be waiting to see what happened in the Harris County case before moving forward.

Since Zwerneman’s Thursday article, more details have emerged on the Harris County case. It turns out Chiswell also sent threatening and harassing letters to Houston philanthropist and socialite Carolyn Farb for decades (more than 30 years, according to Farb), leading to a felony stalking charge.

While some originally assumed that the racist letter to Sumlin was sent by a frustrated Aggies fan, Chiswell is in fact a graduate of Texas A&M rival Texas.
