All four were found shot to death in a home in the 14000 block of Fosters Creek Drive in Cypress last month.
Mei Xie, her husband Maoye Sun and sons Titus and Timothy Sun were killed in their house between 7pm Friday, January 24, when the husband left work, and 11am Saturday, January 25, when the boys failed to appear at a Boy Scout event, Harris County Sheriff Adrian Garcia said. The bodies were discovered January 30.
Details that may have seemed trivial at the time may be important now, the sheriff emphasized as he urged people to come forward with clues while investigators await crime lab results on evidence gathered at the scene.
"Encourage your viewers for when they may have been in this vicinity in this time frame," Sheriff Garcia added. "We're looking for descriptions of individuals, vehicles, car activity, noises, conversations."
A neighbor, who didn't want to be identified, thinks the increased reward money may help provide the motivation to solve the case.
"Money will motivate anyone," he said. "Someone will step up at some point and things will happen."
Anyone with information about the family's murder can contact Crime Stoppers at 713-222-TIPS or the Harris County Sheriff's Office.
