Daniel Arguijo, 47, was fatally shot outside his apartment at the Palms at Cypress Station in Houston on June 9, 2023. Witnesses heard gunfire and saw a man standing over Arguijo firing additional rounds before fleeing. Surveillance footage captured the suspect leaving the scene.

Authorities identified the assailant as 60-year-old neighbor Melvin Walker. Investigators learned Walker had told a witness the day before that Arguijo owed him money and he intended to take action; court filings say Walker confronted Arguijo about the alleged debt before the shooting. After the murder Walker remained at large and on June 26 was recorded assaulting and burglarizing an 86-year-old woman; she survived but needed extensive medical treatment. Walker was arrested June 27 on aggravated robbery and burglary charges and was charged with Arguijo’s homicide on June 30. A judge denied bond and Walker was held as a habitual offender with a court date set for late August 2023.

Anyone who knew Daniel, saw the incident, or has information about either crime is asked to come forward.
