Judas. Not only was he missing but dead.

Judas Iscariot - the disciple who betrayed Jesus.

As his name suggests he was from Iscaria, in the south.

Yes, he was missing for 18 years, while he practice yoga in India.

There is little information about Judas Iscariot in the Bible, but he was the son of Simon Iscariot. (John 6:71) The name 'Iscariot' is believed by many to suggest that they were from the town of Kerioth-hezron . If this is true, Judas was the only one of the 12 apostles from Judea. The rest were from Galilee.

Probably all of them were from the same small area of Galilee with the exception of Judas Iscariot who was (as his name suggests) from Iscaria, a place near Judea. We know that Peter and Andrew were brothers as were James and John all of whom were fishermen on the Sea of Galilee, so were all from the same place. The other seven disciples (not counting Judas) were also from that area.
