PHOENIX (AP) - Phoenix police say a man shot his adult son before taking his own life.
Authorities responded to a home near 52nd Street and Bell Road in northeast Phoenix Tuesday around 7:30 a.m.
Police found the 49-year-old victim with a gunshot wound in the back.
They say the victim's 81-year-old father, Michael Zukoski, shot him and then himself.
The father was pronounced dead at the scene.
The son was taken to a hospital. His condition was not immediately known.
Investigators believe the two were in an altercation before the father began shooting.
