Raymond was left alone for at least four hours last July after a group returned from a field trip. Temperatures inside reached at least 113 degrees, Constable Alan Rosen said.

A medical examiner has now ruled his death to be a homicide.

Houston police say the district attorney's office is aware and this case will go to a grand jury.
