1. Contact the Clayton Public Library, Houston (downtown) and see if a librarian would be willing to search their newspapers on microfilm (based on the date of death) to see if there is a newspaper article on the murder;
2. Contact the Harris County Coroner's Office to see if they have any archived reports on the autopsy; and
3. Contact either the Harris County Sheriff's Office or the Houston Police Department (depending on who handled the investigation and where the murder occurred) to see if they have an archived police report on the incident. Is there a police report # on the death certificate?
If #s 2 or 3 above don't "pan out" for you, and you can't get a librarian to look for a news article, send me a message and maybe I can get downtown to look for you. Good luck!
