Why did some Jews believe jesus to be the messiah?

For some Jews, the name alone is nearly synonymous with pogroms and Crusades, charges of deicide and centuries of Christian anti-Semitism.

Other Jews, recently, have come to regard him as a Jewish teacher. This does not mean, however, that they believe, as Christians do, that he was raised from the dead or was the messiah.

Explanation: this is really the only info i could find. also Jew might believe in Jesus to be the messiah because they were told that, and taught that as a kid.
