Summary based on the NamUs case record (MP6703) and 9 other sources
Cynthia Lynn Sumpter, a 5-year-old girl, was last seen on April 27, 1974, playing outside her apartment complex on Elm Street in San Jose, California. Around 1:30 to 1:45 p.m., her mother, Linda Sumpter, realized Cynthia was missing and searched for her for half an hour before notifying the police. Despite a massive search effort, Cynthia was never found. Witnesses reported seeing her speaking with a man driving a blue car, described as a young male with blonde hair and a mustache, though this sighting was never confirmed.

In the weeks leading up to her disappearance, Cynthia had been sexually molested near her home, and her mother had pressed charges against the alleged perpetrator. Days after Cynthia went missing, the suspect's stepbrother made a ransom demand, claiming he had kidnapped her and requested $1,000 for her safe return, along with a request to drop the charges. However, this turned out to be a hoax, and the man was arrested for attempted extortion.

Two individuals became suspects in Cynthia's case. Antonio Madrid, a neighbor and the stepfather of one of Cynthia’s friends, lived only 100 yards from her apartment. Madrid died by suicide two days after Cynthia's disappearance, and police later discovered a bloodstained shirt and blonde hairs in his car. Another potential suspect, convicted murderer Eugene Joseph Wesley, was questioned and took two polygraph tests. The results suggested he knew more about Cynthia's disappearance than he revealed, but he was never charged.

Although both suspects are now deceased, Cynthia's case remains unsolved, with police suspecting that foul play was involved. Her mother, who moved to Idaho and has since remarried, continues to believe that Cynthia could still be alive​
