Warren Dixon, 25, of Camden, pleaded guilty Tuesday to Aggravated Manslaughter and Attempted Aggravated Sexual Assault in connection with the suffocation death of Sherita Williams.
Dixon admitted that, on November 29, 2003, he met Williams in Camden and took her under the 36th Street bridge in Pennsauken. While there he attempted to have sex with her and, when she resisted, he put his hands around her neck, strangling her.
Dixon was arrested six years later - in January 2009 - after a stain on Williams' clothing was matched to Dixon's DNA profile which was on file as a result of a prior criminal conviction.
As a part of his plea Dixon is expected to be sentenced to 20 years in prison, 85 percent of which must be served before he is eligible for parole.
In addition Dixon's name will be added to New Jersey's registry of convicted sex offenders and he will be subject to community supervision for life.
