MARIETTA, Ga. -

Child advocates and others have hopes of building a park in memory of a Georgia toddler who died in a hot car. 

Justin Ross Harris faces a murder charge in the death of his 22-month-old son Cooper Harris.  Police say Harris left Cooper in the hot car June 18.  Harris told police he forgot Cooper was in the car when he went to work at a Home Depot office in suburban Atlanta. 

The Marietta Daily Journal says they hope to build the park in Marietta Georgia or Tuscaloosa, Alabama, where Harris is a native of. 

The group looking to build the park is known as Cooper's Tree House Foundation.  They are looking to raise $250 thousand.  The group has created an online go fund me campaign.  So far the site has raised more than $800.
