Omar said Tuesday the mother told him nothing seemed different about her son, who she said was enjoying his education.
Artan was a Muslim who prayed daily and stewed over the treatment of fellow Muslims.
Omar says he was shocked by Monday's attack because of the amount of effort the community puts into preventing people from being radicalized.
Democratic U.S. Rep. Adam Schiff is a House Intelligence Committee member and says he's seen no evidence Artan communicated with overseas terror organizations.
Artan was killed by police.

A union official says the officer who killed a man to stop an attack at Ohio State University responded according to his training and is grateful for the outpouring of support he's received from fellow police and the public.
Local police union president Jason Pappas says university officer Alan Horujko is on paid administrative leave. Pappas says standard procedure requires that the 28-year-old officer see a psychologist and get a new firearm before he gets back to work.
Officials say Horujko was nearby when a Somalia-born student plowed a car into a group of pedestrians Monday morning and began stabbing people with a butcher knife. Police say the officer shot the driver in less than a minute.

Noah mentors youth at the mosque, which also offers "Meet a Muslim" programs and helps Somali parents learn to communicate with their children, especially as they assimilate faster to life in America.
