Michael J. Fox Foundation sues N.J. lab

CAMDEN, N.J. (WPVI) -- The Michael J. Fox Foundation is suing a New Jersey medical institute.

The lawsuit was filed against the Coriell Institute for Medical Research in Camden.

The Fox Foundation says lab workers there destroyed 26,000 samples of blood and spinal fluid collected for a study of Parkinson's disease.

Fox has been battling Parkinson's disease since 1991.

The suit claims the samples were lost because workers left a freezer door open.

Fox's foundation has contracts with Coriell.

The lab has not commented on the suit.
