A Death Penalty Information Center analy­sis of data from the National Registry of Exonerations has found that law enforce­ment use or threat of cap­i­tal pros­e­cu­tion against sus­pects or wit­ness­es con­tributed to the wrong­ful con­vic­tions of 10% of the peo­ple exon­er­at­ed in the United States and more than one-fifth of all mur­der exon­er­a­tions in 2020

Reviewing data from the National Registry of Exonerations’ 2020 Annual Report, DPIC found that the death penal­ty was pur­sued or defen­dants or wit­ness­es were threat­ened with the death penal­ty in the cas­es of at least thir­teen of the 129 peo­ple exon­er­at­ed in 2020. The National Registry clas­si­fied offi­cial mis­con­duct as a fac­tor in 12 of those cas­es and per­jury or false accu­sa­tion was present in all 13. The National Registry report­ed 61 mur­der exon­er­a­tions in 2020 and the coer­cive use or threat of cap­i­tal pros­e­cu­tion was impli­cat­ed in 21.3% of those exonerations.

Four of the exon­er­a­tions were from the city of Philadelphia and three were from Chicago, two of the juris­dic­tions with the most death-row exon­er­a­tions in the coun­try. Eleven of the 13 exon­er­a­tions involved wrong­ful con­vic­tions of African-American defendants. 

Six of the exon­er­a­tions involved defen­dants who were wrong­ful­ly con­vict­ed and sen­tenced to death. In three oth­er cas­es, the exoneree faced the death penal­ty at tri­al but received a life sen­tence or was con­vict­ed of less­er mur­der charges. One exoneree was tried before a death-qual­i­fied jury with a co-defen­dant who was sen­tenced to death. One exoneree false­ly con­fessed after being tor­tured by police and threat­ened with the death penal­ty. Two oth­ers were wrong­ful­ly con­vict­ed of mur­der when the lead pros­e­cu­tion wit­ness false­ly impli­cat­ed them after hav­ing been threat­ened with the death penalty. 

Collectively, the exonerees spent more than 300 years incar­cer­at­ed for these wrong­ful con­vic­tions, aver­ag­ing 28.4 years in jail. That was near­ly dou­ble the length of time exonerees as a whole lost to their wrong­ful incar­cer­a­tions (13.4 years).

Thirty-sev­en wrong­ful­ly con­vict­ed men and women have now been exon­er­at­ed in the last three years in cas­es in which pros­e­cu­tors secured con­vic­tions or delayed an inno­cent person’s release from prison by threat­en­ing wit­ness­es or defen­dants with the death penal­ty. In addi­tion to the 13 death-penal­ty-relat­ed exon­er­a­tions in 2020, the use or threat of the death penal­ty was impli­cat­ed in 19 exon­er­a­tion cas­es in 2019 and five exon­er­a­tions in 2018.

Here are the exon­er­a­tions in 2020 in which wrong­ful con­vic­tions were secured as a result of the use or threat of capital prosecution:

Black

Male

Perjury or False Accusation, Official Misconduct

Wrongfully cap­i­tal­ly pros­e­cut­ed but just con­vict­ed of non-cap­i­tal third-degree mur­der charge. Conviction used as aggra­vat­ing cir­cum­stance in a sec­ond case in which Williams was sen­tenced to death. That death sen­tence was lat­er over­turned for prosecutorial misconduct. 

Although mis­con­duct occurred in a siz­able num­ber of exon­er­a­tions, it was much more preva­lent in cas­es in which police or pros­e­cu­tors threat­ened or pur­sued the death penal­ty. Overall, the National Registry report­ed offi­cial mis­con­duct in 87 exon­er­a­tions (67.4%). By con­trast it was present in 92.3% of the cas­es in which the death penal­ty was implicated. 

Police or pros­e­cu­tors with­held excul­pa­to­ry evi­dence in 79 of the exon­er­a­tions in 2020 (61.2%), or 90.8% of the cas­es involv­ing offi­cial mis­con­duct. However, they were 50% more like­ly to with­hold excul­pa­to­ry evi­dence in the death-penal­ty-relat­ed cas­es. Law enforce­ment sup­pressed excul­pa­to­ry evi­dence in all 12 death-penal­ty-relat­ed cas­es in which mis­con­duct occurred. And while pros­e­cu­tors com­mit­ted mis­con­duct in less than half of all 2020 exon­er­a­tions (51 of 129 cas­es, or 39.5%), they com­mit­ted mis­con­duct in 84.6% of the exon­er­a­tion cas­es in which the death penal­ty was pur­sued or threat­ened (11 of 13) — more than twice as fre­quent­ly as in oth­er cas­es. By con­trast, there was lit­tle dif­fer­ence in the rates at which police mis­con­duct occurred: it was present in 74 of the 129 exon­er­a­tions over­all (61.2%) and in 8 of the 13 death-penal­ty-relat­ed exon­er­a­tions (61.5%).
