The Texas A&M University Police Department says its investigation into a black student finding racist notes on his car windshield concluded that he put them there himself.

Law enforcement officials at Texas A&M University in College Station, Texas, say that 21-year-old Isaih Martin, a senior at the school, called police on Wednesday afternoon to report handwritten notes places on his car with derogatory insults such as “All lives matter” and “You don’t belong here,” according to KBTX 3 News.
