Lady Discovers Husband is Dead - Not Asleep - After 4 Days

Something ain't right.

A man lay dead in his own apartment in the Russian city of Volgograd for four days before his wife realised he was dead and not sleeping, investigators said on Tuesday. The 57-year old man died on January 14 and the woman only noticed that something was amiss with him when she saw "putrid spots" on his body, investigators said. The cause of death has not yet been established.

Obviously, these people had other issues going on in their relationship or we don't know the full story here, because if someone doesn't wake up after one day (at least), wouldn't you check to make sure he's all right? Or are we just crazy?
