Ismaeil Najafi Aghdam according to the White pages is 65 years old and is related to the shooter.
Esmaeil Najafi Aghdam according to to Sahand University site was born in 1964 making him 53 years old.
The white pages has her father as 65 year old Ismaill Najafi Aghdam and has him as related to 39 year old Nasim Najafi Aghdam. It also lists the father address in Menifee, CA. I found realty pictures at that address that shows the inside and outside of the house. I also found a backyard photo of Ismail's on Facebook that matches the realty pic. I think this one is her father.
