I requested the autopsy report for this case to the HCIFS. They fowarded this email to the archived files library, as they were in possession of the report. Some additional information was included, which I didn't expect to see, but I think it was because the HCIFS isn't the sole owner of the full report, but the investigators for the case. Anyways, here's what everything indicates; I can't attach it because of computer issues.
The decedent had been living on 119 North Bryan Street for only a week (it was an apartment at the time, I don't think it is anymore). He did work at a carpet company, Texas Carpet Company, and his boss, who I think may have been related to his landlord, picked him up for work every morning. He had been using the name Antonio Saphrey, and indicated that he was a seaman from Honduran, and I think he self identified as 19 years old, not entirely sure. When someone from the Honduran Consulate pulled some strings, she established that Antonio Saphrey was alive and well, stationed on a ship at sea in Louisiana.
In regards to his death, at around 2:15 AM on December 12, 1981, his neighbors heard gunshots and saw him fall into their doorstep. At the time, there was no suspect or gun in police custody.
