Victim: Harvard coffee poisoning not an accident

BOSTON (AP) — One of six Harvard Medical School researchers sickened after drinking coffee laced with a toxic chemical said Monday he does not see how the poisoning could have been accidental, but has no idea who might be responsible.

University police and other agencies are investigating the Aug. 26 poisonings, which were revealed in an internal memo to medical school faculty last week. The memo identified the substance as sodium azide, a common preservative used in school labs, but did not indicate whether officials believed the laced coffee to be accidental or intentional.
