Houston police seek person of interest in Cullen Boulevard stabbing death

A routine welfare check at an apartment on Cullen Boulevard turned into a homicide scene when Houston police found an unresponsive man with an apparent stab wound at 10010 Cullen Boulevard. The man was pronounced dead at the scene, and investigators have spent more than a month trying to piece together how the call unfolded and who was involved.

Cases that begin as welfare checks can be difficult to reconstruct because officers often arrive after the crucial moments have already passed. Neighbors may have heard a disturbance, seen police and ambulance crews arrive, or noticed nothing unusual until the scene was already secured, leaving detectives to work backward from limited observations, door knocks, and whatever evidence remains inside the apartment.

Houston police said on June 16 that they needed help locating Larry Dennis, 35, whom investigators want to question in the fatal stabbing. The department has not said Dennis was charged, but naming him publicly marked a clear shift from an unidentified death to a case with a specific person of interest. The earlier May 7 update said investigators had no known motive and no known suspect, and the deceased man’s identity was still pending verification by the Harris County Institute of Forensic Sciences.

Police said the public can contact the HPD Homicide Division at 713-308-3600 or Crime Stoppers of Houston at 713-222-TIPS. Those are the channels detectives are using to gather the missing pieces from anyone who may have seen Dennis, heard an argument, or noticed activity around the apartment before officers arrived.

The killing happened in southeast Houston, inside the Houston Police Department’s Southeast Patrol Division. That area includes Sunnyside, South Park, Crestmont, Edgewood, Bellfort Park, Inwood Terrace and Southpark, neighborhoods where apartment complexes, side streets and dense traffic can make it harder to track who came and went before a violent crime. HPD’s neighborhood crime reports for patrol beats are typically released about 15 to 20 days after the end of the previous month, which is one reason homicide cases often remain fluid long after the first emergency call.

For now, the most important unanswered questions remain the same: who was with the victim inside the apartment, what led to the stabbing, and what information can move the case from a person of interest to a full resolution.
