Summary based on the NamUs case record (MP9564) and 2 other sources
Maximino Casteneda, a 30-year-old man, went missing on August 4, 1999, from San Ysidro, California. On June 29, 1999, Maximino and his friend Robert Delgado traveled to Tijuana, Mexico. A few days later, Delgado’s vehicle was found abandoned in Tijuana. Shortly after, Delgado's body was discovered, showing signs of torture. Maximino has not been seen or heard from since that time, and despite efforts, his whereabouts remain unknown.

At the time of his disappearance, Maximino was described as a Hispanic male, standing 5'9" tall and weighing 200 pounds, with brown hair and black eyes. He had a distinctive scar on his chest and was last seen wearing blue Levi's jeans and a green shirt. His case remains classified as endangered missing, and the San Diego Police Department continues to seek information on his whereabouts.

The circumstances of his disappearance, particularly the discovery of his friend's tortured body, suggest potential foul play. Authorities encourage anyone with information to contact the San Diego Police Department.

Last Seen: Aug 4, 1999
