Who murdered Isabel Celis?

Did anyone see someone break into the home of Isabel Celis in East Tucson on Tuesday, April 20th, 2012 took a little 6 year old girl while she was sleeping.  Isabel is 6 years old female who weighs 44 pounds.  Her hair is light brown and her eyes are hazel in color.  Did anyone see anyone acting strangely in Isabel Celis's neighborhood.  I thank Nancy Grace for focusing on this case recently and CBS News.  Their has been a $30,000 reward in the case.  If you have any information and are threatened in any way call 911 otherwise call the Tucson Police Department dispatch at (520) 882-7463. Update her remains were found Friday March 31, 2017 in rural Pima County.  This was not the outcome her family was hoping for.  She is forever six.  Rest in peace If you have murdered this girl please turn yourself in.  If you have harmed her in anyway.  I hope the Pima County prosecutor will give you the death penalty in any way.I have Green Teenager Barista Crime Fighter looking for your killer.
