A judge on Monday sentenced Brian Martin to death for the shooting death of Sheffield Police Sergeant Nick Risner, finalizing a jury's recommendation that took less than 15 minutes to reach. Martin was convicted last month by a Colbert County jury of murdering Risner during a confrontation in Muscle Shoals, and he still faces a separate pending trial in the death of a man prosecutors say was his friend.

According to WAFF, jurors took less than 15 minutes to reach their death-penalty recommendation after Martin's conviction in September. WHNT reported that the recommendation was unanimous. That conviction, reported by WHNT, covered 10 total counts following 90 minutes of jury deliberation, including three counts of capital murder, three counts of attempted murder, three counts of shooting into an occupied vehicle, and one count of certain persons forbidden to possess a firearm.

What the Jury Saw Before Convicting Martin

Before reaching its verdict, the jury heard testimony from officers who were involved in the events of that day in October 2021, the same WHNT report notes, along with body-camera footage and autopsy photographs. Jurors also heard from a psychologist and a forensic examiner as part of the case against Martin.

Prosecutors say the confrontation that led to Risner's death followed another killing. Martin is accused of killing his friend, William Mealback Jr., before throwing his body out of a car on October 1, 2021, the station's report states. A separate statement from the Alabama Law Enforcement Agency places the reported gunfire between Martin and Sheffield officers on October 1, 2021, at approximately 2:00 p.m., identifying the suspect as Brian Lansing Martin, 41, of Sheffield.

Second Trial Still to Come

Martin has not yet stood trial in Mealback's death. He will face that case at a later date, per the same account from WAFF. At Monday's sentencing, Martin chose not to apologize to Risner's family, according to WHNT.

How Alabama's Capital Case Would Proceed

Under Alabama Code Section 13A-5-40, the murder of a police officer, sheriff, deputy, state trooper, or other listed peace officer while on duty — or because of an official or job-related act — is specifically listed as a circumstance that can support a capital-murder charge. Martin faced capital-murder charges.

Any appeal in Martin's case would move through a three-tiered process, according to the Alabama Attorney General's Office, which assigns capital cases to its Capital Litigation Division. The sentencing was also reported by Local 3 News.
