WHERE IS Carl Alfred Eder? On Dec. 12, 1958 the 16-year-old butchered five members of the Pendergast family of El Cajon, California. Father Thomas Pendergast had picked him up hitchhiking the month before, the boy said he was homeless so the kind man took him in until he got a job. That decision would cost Pendergast his family. Thomas was at work when the massacre occurred. Eder told detectives that Diane Pendergast, 4, was bothering him and he exploded in rage. He threw the child against a wall, then grabbed a gun and shot the mom, Lois Pendergast in the head. Cops say the crazed teen grabbed a knife from his
suitcase and then slashed the throats of Diane and her brother Allen, 2. They were stabbed so violently, they were disemboweled. Thomas Jr., 6, and David, 9, were next and killed in the same gruesome way. When Thomas got home, Elder made him drive around until he fled on foot. When he got home he made the horrifying discovery. Eder was nabbed and charged with first-degree murder three days later and received two life terms.
In 1974, he escaped from a MINIMUM security prison. he has not been seen since. Two years later a badly composed body was discovered on the Pendergast property--chained to two cinder blocks. The male had been dead two weeks but it wasn't Eder.

  1. When will anybody catch this guy?

  2. My mom lived down the street when this happened creepy lol

  3. He deserves the electric chair

  4. I walked home from school with David and his little brother that day he was murdered. Thier house is right around the corner from where I lived and luckily for me, my mother liked me to come straight home after school.

  5. This is such a sad story. I'm glad that you weren't in that house when everything went down Lynn. What ever happened to the father?

    1. In 1971, the father of the family that was murdered (Mr. Pendergast)was a guest in our home one evening. He was there because he was interested in doing business with my dad, who was a buyer, trader and seller. He was very nice and remember feeling sorry for him after he left our house that night, for my parents related the sad story of his family's tragic demise. I will add here that I grew up in El Cajon and my family was well aware of the murders when it happened.

  6. Who was it chained to the cinder blocks then? ? Was it Mr.Thomas Edgar came back ti kill?? Whose body was it?

  7. Finally, someone asks the same question as me! Nobody is mentioni ng the other dead guy! Did Mr. Pendergast somehow catch him - I know it said it wasn't him but whatever - and if not, then its a random other dead guy. So Pendergast is a killer too.
