A man accused of shooting his mother down in the street is dead, according to the Douglas County Sheriff’s Office.

Jarek Kozlowski, 28, died Friday night at Renown Regional Medical Center of respiratory failure.

His death was not related to the gun shot wounds he sustained in a shootout with the two deputies who responded to his Manhattan Way address, said Sheriff’s spokesman Sgt. Pat Brooks.
