DeTwan Walker was 20 when he stepped out onto the front porch of his Navajo Street home in North Charleston in the early hours of December 26, 2018, and was found moments later with a fatal gunshot wound to the head. His girlfriend initially told 911 dispatchers and officers that he had taken his own life, but an autopsy and forensic findings did not match that account and the case was reclassified as a homicide.

Officers executing a search warrant at 3434 Navajo Street recovered marijuana, pills, and a handgun that was found on the porch. An occupant, Kwantice Ravenel, was charged with possession with intent to distribute a Schedule IV controlled substance, and another person at the residence was later taken into custody on drug charges; investigators did not say those charges were directly tied to the killing. Nearly a year later police released a photo seeking to locate Glenn Wallace Ackerman for questioning, but authorities did not publicly identify a shooter or announce any arrest in Walker’s death.

Does anyone with information about DeTwan Walker, the Navajo Street residence, or the events of that night have tips to share with North Charleston investigators?
