Police are on the scene of a fatal shooting on Detroit's west side.
It happened in the 1800 block of Ferguson. Police say they have been to the home numerous times in the past.
7 Action News is being told that a father and son were having an argument. The father reportedly had a gun in his waistband--and that it fell out and onto the floor. That's when the son picked up the gun and, police say, shot his mother twice when she tried to intervene.
She was pronounced dead at the scene.
Police say the son does suffer from mental illness. He was detained at Sinai Grace Hospital.
The investigation is ongoing.
