Herbert Meyers III, a New Orleans man who claimed that burglars killed his father on March 22, was arrested and booked on a murder count at least in part because all of the spent shell casings that police found near the body belonged to Meyers’ gun.

It is not clear why the son would have killed his father, Herbert Meyers Jr., at the latter’s home near the lakefront. But court records show that police recovered a total of 17 casings, all belonging to the younger Meyers’ pistol-style AK-47.

Records show that after police obtained a warrant for Meyers’ arrest, they issued a bulletin warning that the 35-year-old suspect was “possibly suicidal” and might be “armed and extremely dangerous,” noting his experience with mixed martial arts and his enthusiasm for guns.

Police found the elder Meyers lying dead on the kitchen floor in his home in the 2400 block of Oriole Street with eight gunshot wounds to various parts of his body, according to police and court records.

It’s unclear what his son told detectives, but in an interview with The New Orleans Advocate, he claimed he had left his dad for about 15 minutes to go to a store to buy supplies for a jazz club they owned in Gulfport, Mississippi. He said he returned to find his father shot, retrieved a gun from his truck and began firing at two men he said had been rummaging through his father’s belongings before they escaped out a back door.

In the application for an arrest warrant, police said Meyers’ account did not hold up after interviews with witnesses in the area and an unsuccessful search for any signs of a home invasion. Police also wrote that officers weren’t allowed to search the elder Meyers’ home until they obtained a signed warrant to do so.

On top of that, the warrant application says that ballistics testing showed the 17 spent shell casings found at the site all matched Meyers’ gun, which could hold a total of 30 bullets.

The U.S. Marshals Service arrested Meyers on Friday in Metairie. His bail on one count of second-degree murder was set at $750,000.

A defense attorney filed a motion on his behalf asserting his right not to be interrogated by police without a lawyer present.

If Meyers is convicted of second-degree murder, he would be imprisoned for the rest of his life with no possibility of parole.

The elder Meyers’ funeral Mass is set for 11 a.m. Wednesday at St. Peter Claver Catholic Church in New Orleans.
