Blood in the Water: The Attica Prison Uprising of 1971 and its Legacy by Heather Ann Thompson:
Most damningly, Simonetti’s office believed it knew exactly which trooper or CO had killed specific prisoners on the day of the retaking. Internal memos suggest that investigators had evidence that trooper James Mittlestaedt shot prisoner James Robinson through the neck “at a range of two to five feet, breaking his neck and killing him instantly.” Simonetti’s office also indicated that it knew who had killed prisoner Bernard Davis. Davis had died from more than twenty-three gunshot wounds, and one internal memo identified that officer as P. F. Stringham. According to other documents CO Stringham had also likely killed another prisoner—Milton Menyweather. One Attica investigator testified that Paul F. Stringham, armed with his “own personal brownie [sic] twelve-gauge shotgun loaded with five deer slugs,” had “identified a photo of P-5, Milton Menyweather [sic] lying on the catwalk to the right of Times Square, as the one he shot."
