Xiuxia Michelle Chen, 44, was shot and killed on June 2, 2017, while working as manager of the Ambassador Inn on Valley Boulevard in Alhambra, California. A masked man entered the hotel office about 11 p.m. and attempted to rob her; he shot Chen at least once in the torso. A co-worker found her bleeding and called 911, but she was pronounced dead at the scene.

Investigators described the suspect as an adult male, 5 feet 6 inches to 6 feet tall, medium build, last seen in a dark hooded sweater and a dark glove. Surveillance footage from the lobby captured the confrontation and the gunman fleeing on foot, but identifying him has been difficult. Chen was remembered by family and colleagues as kind and non-confrontational; her husband, Armando Escandor, said she had never encountered serious trouble at work before.

A news conference and a $20,000 reward were publicized as authorities and the family sought tips. Does anyone have information about that night or recall seeing a person matching that description near the Ambassador Inn on Valley Boulevard?
