Daniel Smith, the late 20-year-old son of Anna Nicole Smith, was remembered Saturday by about 50 family members and friends at the First Baptist Church of Mexia, Tex., the Associated Press reports.

Daniel died on Sept. 10 in his mother's hospital room in the Bahamas, three days after she gave birth to a daughter, Dannielynn Hope. A pathologist hired by the family told PEOPLE Daniel's death was the result of a lethal combination of methadone and the antidepressants Zoloft and Lexapro.

Daniel's father, Billy Smith, who still lives in Mexia (population: about 6,000), attended the memorial, according to the Waco Tribune-Herald, although Anna Nicole did not.

According to the Tribune-Herald, most relatives at the service had not seen Daniel in years, but remembered him wearing cowboy outfits and riding horses as a child. His great-grandfather, Gus Moser, delivered the eulogy, admitting that he didn't know Daniel but speaking about salvation.

Daniel's cousins remembered playing Teenage Mutant Ninja Turtles with him, and so full-size cutouts of the characters were set up along the front of the church, the Tribune-Herald said.

Anna Nicole – then known as Vickie Lynn Hogan – was an 18-year-old waitress when she married 17-year-old fry cook Billy Smith in 1985. They divorced in 1987.

Shortly after Daniel's death, Billy Smith, interviewed outside his Mexia home, said he hadn't seen his son since Daniel was 2 and only learned about his death "when my brother read it on the computer."

Still, he said he had "no hard feelings" toward his ex-wife and added that his memories of Daniel were fond ones: "He was a good baby, well-loved."
