Some of the events were organized by the Council on American-Islamic Relations, which has been working with Mr. Dghoughi’s family. Faizan Syed, the executive director of C.A.I.R. in Austin and Dallas-Fort Worth, said the authorities had initially given the family little information beyond a statement on Oct. 11 about the shooting.
In that statement, the sheriff’s office said that a “homeowner confronted a suspicious vehicle parked outside the residence” and that the shooter was being “cooperative.” It said a man with a gunshot wound was “transported to the hospital for critical, life threatening injuries.”
“After we sent out press releases and started getting media coverage, he was still not arrested,” Mr. Syed said.
