What police say

The Lafayette Police Department said the stabbing happened during a large fight early Sunday morning. Officers responded to the 500 block of Jefferson Street after the violence broke out and later confirmed that Martin died from his injuries.

Police said two other people were injured in the same incident. Both were listed in stable condition after the attack.

Investigators have not said how they identified Arceneaux as a suspect. They also have not said which victim is tied to the attempted murder count or whether a weapon was recovered.

The investigation

In cases like this, detectives usually work backward from witness accounts, physical evidence, surveillance video, and medical findings to determine who took part in the attack. A large fight can complicate that effort because officers may have to separate multiple accounts and match injuries to specific acts.

Police have not released details about the evidence used to make the arrest. They have also not identified any additional suspects or said whether more arrests are possible.

The Lafayette Police Department said the investigation is still active. Officials have not announced a tip line in the release, but people with information in violent-crime cases are often asked to contact investigators directly through local police.

What the charges mean

First-degree murder is among the most serious homicide charges and, under Louisiana law, can carry the heaviest penalties if prosecutors prove the case in court. An attempted first-degree murder charge alleges an effort to kill that did not result in death.

A booking at the parish correctional center means the accused was taken into custody and entered into the jail system while the case moves forward. It does not determine guilt. In serious felony cases, prosecutors still must present evidence and prove the charges beyond a reasonable doubt.

After an arrest, the next steps usually include a court appearance, review of bond or detention issues, and later hearings where prosecutors and defense lawyers address the evidence. Those proceedings can take time as investigators finish the case file.

What happens next

Police have not announced any new charges or a court date for Arceneaux in the release. The case remains under investigation as detectives work to fill in the details surrounding the stabbing and the injuries to the two surviving victims.

Authorities have not said whether more information will be released once the investigation advances or whether the case will be presented to a grand jury or other charging authority.
