Tears after death?

Please understand I don’t want this to sound morbid,but it is something that has troubled me since 1994.After my husbands death tears kept strolling down his face.Could this be a medical situation having to deal with the tear ducts or the fact that he didn’t want to leave us?

Human tear ducts do not continue to produce tears after death, and dead people do not weep, but I did find a couple of references to seals.
