ALBUQUERQUE, NM — Albuquerque police arrested a 22-year-old man overnight Saturday in connection with the fatal stabbing of a 72-year-old man at a Southeast Albuquerque apartment complex, according to investigators.

Aidan Gregg-Kriegel was charged with an open count of murder after the death was reported early Saturday morning at the complex on the 900 block of Louisiana. Police said officers were called to the scene around 7:20 a.m. after the victim was found dead with what appeared to be stab wounds.

The older man was not publicly identified. Police have described the case as a homicide investigation centered on a dispute that unfolded in the neighborhood.

Police say dispute with neighbors preceded the killing

In a news release, Albuquerque police said Gregg-Kriegel had been involved in several recent disputes with his neighbors. Investigators linked those conflicts to the apartment complex where the killing was reported.

Police also said Gregg-Kriegel had previously been charged with misdemeanor battery. Authorities did not say in the release how the earlier charge may relate to the stabbing case, but they made clear it was part of the background they were reviewing.

The arrest came less than a day after the body was discovered, suggesting detectives moved quickly once they identified a suspect. Police have not released additional details about what led to the confrontation or what evidence supported the murder charge.

Victim found dead after officers were called to the 900 block of Louisiana

Officers were dispatched to the apartment complex after the stabbing had already occurred, police said. When they arrived, they found the victim dead at the scene.

The location is in Southeast Albuquerque, and police have not said whether the attack happened inside an apartment, in a common area or elsewhere on the property. They also have not identified any witnesses in the case.

Because the victim was found after the fact, investigators are working backward from the scene, the reported timeline and statements from people who may have seen or heard the events leading up to the killing. No further information about the weapon or the sequence of events has been released.

Court records were not clear on whether Gregg-Kriegel had a lawyer

After the arrest, court records did not make clear whether Gregg-Kriegel had an attorney. That is a common early gap in a case that has just moved from investigation into the court system.

Police have not said when he is expected to appear in court or whether prosecutors plan to add any other charges. For now, the public record shows an open count of murder tied to the fatal stabbing.

The case will likely continue to develop as charging documents, hearings and police records become available. At this stage, authorities have said only that Gregg-Kriegel was taken into custody overnight and linked to the death at the apartment complex.

Apartment complex killing adds to concerns raised by nearby residents

While police have not offered a broader public safety warning, the reported disputes between Gregg-Kriegel and his neighbors suggest the killing grew out of tensions in the building or surrounding complex. That detail gives the case a local context beyond a single overnight arrest.

Investigators have not said whether the victim and Gregg-Kriegel knew each other, but the neighbor disputes mentioned by police indicate some prior connection within the apartment community. The charge of misdemeanor battery also points to earlier contact with law enforcement.

Authorities have not said whether the complex remains an active crime scene or whether additional evidence searches are underway. For now, the case rests on the arrest, the homicide charge and the unanswered questions surrounding the fatal encounter.

What is known now about the homicide investigation

As of Sunday, police had confirmed four key facts: a 72-year-old man was found dead early Saturday, the death appeared to be a stabbing, Gregg-Kriegel was arrested overnight, and he was charged with an open count of murder.

Those are the central facts investigators have put forward publicly. The victim’s name has not been released, and police have not described the exact circumstances that led to the deadly confrontation.

What remains is the standard next phase of a homicide case: court proceedings, additional evidence review and any further statements from Albuquerque police or prosecutors. For now, the arrest marks the first major public step in the case.
