On January 6, 2023, at about 4:30 a.m., five people were shot in a back parking lot at the Landmark on the Valley Apartments, at Spring Valley Road and Esperanza Road in Dallas. Among those killed was 22-year-old Stanley Arnoldo Chachagua; two other men, Cesar Aaron Birrueta-Soto, 31, and Queidin Flores, 29, also died at the scene. Two additional male victims were taken to hospital, one in critical condition and one stable.

Investigators found evidence of drug use at the scene and said they did not believe the shooting was random. Police identified 25-year-old Evin Geovanny Mata-Guzman as a suspect and later obtained a warrant for his arrest. The Dallas Police Department boosted patrols around the complex after the killings.

Chachagua was born August 16, 2000, in Chalchuapa, Santa Ana, El Salvador, and had immigrated to the United States six years before his death. He is survived by his parents José and Ana Ruth, his brother Oscar Gael, and his sister Michelle; he was buried at Restland Memorial Park in Dallas.

Did anyone in the area witness activity at the complex that morning or have information about the shooting?
