The 20-year-old Ohio State University attacker stayed in North Texas briefly after immigrating with his family from Somalia.
Records from Catholic Charities in Dallas show that Abdul Razak Ali Artan came to Dallas as a refugee in June 2014, along with six siblings and his single mother. They stayed in Dallas for a short time before moving to Columbus, Ohio.
Artan on Monday plowed a small grey Honda into a crowd outside an engineering classroom building, then got out and started stabbing and cutting people with a butcher knife before he was shot and killed by a campus police officer.
Eleven people were hurt, one critically.
Catholic Charities looked through its files and believes Artan only stayed in North Texas for 23 days. The records don’t say why the family moved to Ohio.
The non-profit said it learned of Artan's Texas connection through the media -- an old address linked back to Catholic Charities.
“The caseworkers or the people who were here then that we were able to get to this afternoon and ask them about, nobody really remembers them, there's no incidents of notice. Nothing special that stood out,” Dave Woodyard, President & CEO of Catholic Charities of Dallas.
Woodyard said he's contacted police in Columbus to make them aware of a possible North Texas connection in case authorities are retracing Artan's steps during his time in the states.
Catholic Charities contracts with the federal government to help refugees get an apartment, enroll in school and get access to healthcare. It does not pick the refugees, instead they are vetted by the state department and its Office of Refugee Resettlement determines where they go.
“We help hundreds of people over the years and thousands are coming to America through all types of different agencies to seek comfort and aid and unfortunately bad things can happen in any walk of life and this is an example of one horrific action,” Woodyard said.
Sources told Fox News Artan was a legal permanent resident of the United States. Now investigators are looking into the possibility that he had terrorist connections.
Police searched his home and are reviewing security camera footage as well as a Facebook post. In it Artan seemed distraught over treatment of his fellow Muslims. In August, he reportedly said he was worried about being able to pray openly on campus.
