Ferdous claims he used his mother's credit cards and the proceeds from selling textbooks to finance his 900-mile trip from Ohio to Oklahoma, records show.
Catherine Bishop, an OU spokeswoman, declined to say whether Ferdous was ever a student at the university, but Devonshire's written statement and the affidavit filed by the OU Police Department both indicate he was expelled some time during the last school year.
The name of Ferdous' attorney was not listed in court documents.
In her written statement, Devonshire said the harassment from Ferdous ended after he was expelled — but not for long.
“I hadn't heard anything for awhile until he was pulled off a Dallas flight for yelling, cussing and thoughts of suicide,” she wrote. “When the police took him into custody they found a letter on him that was addressed to my parents' house.”
Devonshire said the letter scared her because “he seemed completely obsessed with me.” Her statement did not specify when the incident on the airplane took place, and records from Dallas-Fort Worth International Airport were not available for this story.
“In the letter he said he was going to commit suicide if he did not meet with me,” she wrote. “The police sent him to a mental institution for seven days before sending him home to his mom.
“That was the last I heard from him until now.”
