Not sure what to think...

My mom called me this morning and said she was attacked.

She said that she was coming home from dropping off her husband from work. This was at 5am. As she was sticking the key in the door a man came behind her, grabbed her and tried to shove her in the house. She said she screamed and a neighbor opened the door. The man apparently ran away.
She said the cops were called. Not sure if by her or her neighbor. She said she couldn't take a look at the man.
The cops came and drove around the block a few times and then left when they didn't see anyone.

With her history, I just don't know what to think.
