Police say Williams has been missing since around 3:30 pm Saturday. Officers brought out K-9 Units to the scene for additional help; they are also located outside her home with pictures of Williams.
"She walked out of the front door to our understanding, and she ventured somewhere out into the community and at this time we have a search team here looking for her along with our investigators and patrol officers," Durham Police Lt. Williams said.
Police say she doesn't respond to her name, Ellen Williams.
If she is found by someone other than police that person should expect to find someone who maybe disoriented or confused.
Anyone with any information should contact the Durham Police Department.
