AURORA, Mo. (AP) — A neighbor says, "It's crazy that someone can be so likable but be full of this kind of hate."

Mitzi Owens, who lives near the southwestern Missouri town of Aurora, is talking about Frazier Glenn Cross, who's been identified as the suspect in the shootings that killed three people yesterday at a Jewish community center and a Jewish retirement complex near Kansas City. She said he has always seemed friendly, but that locals are well aware of his racist leanings.

The terror monitoring group SITE describes the suspect as a vocal anti-Semite who frequently calls for genocide against Jews. It says he's posted thousands of messages on the website of a neo-Nazi forum -- the most recent of which came Saturday.

According to the Southern Poverty Law Center, which tracks hate groups, Cross has been involved in the white supremacist movement for most of his life.

The former Ku Klux Klan leader was jailed in yesterday's shootings on a preliminary charge of first-degree murder.
