ANGLETON, Texas – A missing Angleton couple and their 5-year-old son have been found dead in Wharton County Saturday, according to a family member.

Maya Rivera, 24, Ray Shawn Hudson Sr., 28, and Ray Shawn Hudson Jr., 5, were last seen in Missouri City and Angleton over the weekend.

Rivera's mother, Frances Rivera, told KPRC that the couple and their son were found dead around 5 p.m. Saturday by officials. She said the family was gathered together in Wharton County when it was announced by deputies.

The cause of death is unknown.

Family members knew something was wrong when they didn't hear from the family of three on Monday, which happened to be Ray Shawn Jr.’s birthday. The families called him Baby Ray.

“We couldn't celebrate with him because we haven’t seen him. We haven’t heard from him,” said Frances Rivera. “We just need them found. We need them found. We need them brought home safely.”

Hudson Sr. went to visit his grandmother Sunday.

“He always checks on his grandmother all the time. That’s his heart,” said Maria Kennedy, a cousin of Hudson Sr.

A friend of the family last saw Maya and Baby Ray in the evening after their kids played together. After that, no one heard from them.

“Maya’s employer called me on Thursday because they were concerned for her welfare as well and I already had it in the back of my mind this has been too long and I hadn’t heard back from her,” said Rivera, who said her daughter is a massage therapist.

Rivera filed a missing persons report with Angleton police on Wednesday. She said on Thursday police told her Maya’s car was found in Rosenberg and the man driving it was arrested on suspicion of possession of drugs.

“With the help of the district attorney here in Angelton, they were able to link with Bue Link on the car to pinpoint where the car was at. Authorities pulled the car over (and) the white male was found in the car,” Rivera said.

Rosenberg police said they were in contact with Angleton police.
