HARRIS COUNTY -

Authorities have released the names of two of the four family members who were found dead in a northwest Harris County home last week.

On the night of Jan. 30, deputies responded to a residence in the 14000 block of Fosters Creek for a welfare check after a friend said the husband had not been to work in a few days.

Deputies say they found the bodies of four people -- two parents and two children -- in the home. All suffered gunshot wounds to the head.

On Thursday, the Harris County Sheriff's Office identified the parents as Maoye Sun, 50, and his wife, Mei Xie, 49. Authorities said they are waiting to identify the two boys through their dental records.

The medical examiner says the two adults were shot once and the two children were each shot twice.

The Harris County Institute of Forensic Sciences Monday said all the cases have been ruled homicides.

The husband and wife were Chinese immigrants and they had two young sons who attended nearby Sampson Elementary School. Family friends say one boy was in second grade and the other was in fourth grade.

Houston's Chinese community is joining together to remember the family and raise money for a reward in the case. The Houston Chinese Alliance is organizing a candlelight vigil that will be held Saturday from 4:30 p.m. to 6:30 p.m. at the Coles Crossing Community Center at 13050 Barker Cypress Road in Cypress.

Zhong Xie, one of the organization's founding members, said the crimes have gotten international attention.  He said Saturday's vigil is also aimed at increasing public safety awareness in the Chinese community.

"Friends and relatives are calling all the time. I received several phone calls last night concerned about safety in Houston and in America," said Xie.

Anyone with information about this case is asked to call the HCSO homicide division at 713-967-5810, Crime Stoppers at 713-222-TIPS or submit a tip via iWatchHarrisCounty.
