Caddo to seek death penalty in Marc Brock slaying

The Caddo Parish District Attorney's office will seek the death penalty against the accused slayer of a Vivian police officer killed late last year, District Attorney James E. Stewart Sr. has announced.

Nicholas Edward Alexander, 58, of Vivian, is accused of firing shots that killed Officer Marc Brock, 25, the evening of November 14, 2025. Brock and a fellow officer were attempting to serve an arrest warrant for cyberstalking. After the officers announced themselves and attempted entry, Alexander fired two shotgun blasts through the closed front door, striking and mortally wounding Brock. The officer died later that night.

"This case involves the killing of a law enforcement officer who was performing his duty to protect the community," DA Stewart said. "Our office is committed to pursuing justice for Officer Brock, his family, and the community he served."

Alexander was indicted by a Caddo Parish Grand Jury on February 10, 2026, on one count of first-degree murder and the three related misdemeanor charges.

On March 10, 2026, the District Attorney’s Office formally filed notice of its intent to seek the death penalty related to the first-degree murder charge involving Officer Brock.

Under Louisiana law, the killing of a peace officer is punishable by life in prison at hard labor without benefit of parole, probation or suspension of sentence or by death, in accordance with the determination of the jury.

The case is docket No. 413238.
