On July 16, 2014, Brandon Cross, 41, and 24-year-old Kenneth Kaiser were found shot to death inside a pickup truck in the 7400 block of Lyrewood Lane in northwestern Oklahoma City. Police say the victims connected with two men by phone under the pretense of a drug transaction to buy marijuana; that meeting escalated into a fatal shooting.

Investigators charged brothers Jerwuan D. Nelson and Deandre R. Nelson in the double homicide. At trial the prosecution presented evidence tying the killings to the drug-related encounter. Jurors convicted Jerwuan D. Nelson of first-degree murder; he received life without parole. Deandre R. Nelson was convicted of second-degree murder and sentenced to 30 years.

The convictions closed a chapter in the case but cannot undo the loss suffered by Cross’s and Kaiser’s families. If anyone knew either man, their movements that day, or has information about the events leading up to July 16, 2014, please share what is known.
