MEXIA, Texas - Family and friends gathered at a church in this small town to mourn the death of Anna Nicole Smith's 20-year-old son Daniel, who died last month while visiting his mother in the Bahamas after she gave birth to a daughter.

About 50 people attended the hourlong memorial service Saturday at First Baptist Church of Mexia for the son of Anna Nicole, a former Playboy Playmate and reality television star, and her former husband, Billy Smith, who still lives in Mexia.

Billy Smith looked grief-stricken during and after the service, the Waco Tribune-Herald reports in it Sunday online editions.

Relatives remembered that before moving away with his mother, Daniel Smith liked to wear cowboy apparel and ride horses in this town of about 6,000 located about 85 miles south of Dallas.

He died Sept. 10 in his mother's hospital room in the Bahamas. According to a private autopsy, he died of an accidental lethal combination of methadone and two antidepressants.

His cousins recalled catching frogs and playing Teenage Mutant Ninja Turtles with him as a boy. Full-size cutouts of the turtles -- Leonardo was Daniel's favorite -- lined the front of the church.

As a relative sang a song she wrote upon learning of his death, other relatives -- most of whom haven't seen Daniel since he left town -- wiped tears.

Daniel's great-grandfather, Gus Moser, eulogized Daniel. Though he said he didn't know Daniel, he spoke to the crowd about salvation.

Billy Smith and Anna Nicole, then known as Vickie Lynn Hogan, met while working at Jim's Krispy Chicken in Mexia. When they got married in 1985, Anna Nicole was 17 and Billy Smith was 16. They divorced about a year after Daniel's 1986 birth.

In 1994, she married Texas oil tycoon J. Howard Marshall II, when she was 26 and he was 89. He died the following year and she's since been embroiled in a legal dispute over his multimillion dollar estate.
