Arlington, Texas
DNA evidence has led to the arrest of Devin Cameron-Mack, 29, in connection with the 2017 murder of 25-year-old Justin Dotson in Arlington, Texas.
Cameron-Mack, who was already incarcerated in the Tarrant County jail on an unrelated aggravated robbery charge, now faces a capital murder charge for Dotson’s death.
Dotson was found fatally shot inside his apartment on the night of October 4, 2017, in the 2000 block of Valleywood Drive. Authorities believe the murder was part of an attempted robbery linked to suspected narcotics activity.
During the initial investigation, detectives discovered a bloodstain at the crime scene that did not match Dotson’s DNA. This sample was entered into a national law enforcement database but did not yield any matches at that time.
In November 2025, investigators received a DNA match linking Cameron-Mack to the sample. When questioned, Cameron-Mack denied involvement in the murder. However, a subsequent DNA sample from him confirmed the match to the crime scene evidence.
As of now, Cameron-Mack remains in custody at the Tarrant County jail, with bail set at $1 million.
