BROOKLYN - A 72-year-old Crown Heights man with Alzheimer's disease has gone missing, according to family members, and they say he might not remember how to find his way home.

Annemarie Garjales says her grandfather, Joseph Garjales, is very active for his age and does not often sit around.

But two days after he went for a walk, he still hasn't returned.

He was last seen wearing a black T-shirt, black sneakers and blue jeans.

Anyone who sees him is asked to call police.
