Los Angeles (CNN) -- A man charged with breaking into LL Cool J's home Wednesday morning faces a long prison sentence if convicted because of his previous convictions, the prosecutor's spokeswoman said Thursday. Jonathan Kirby, 56, suffered a broken nose, jaw and ribs when he encountered the muscular rapper-actor inside his Sherman Oaks, Caklifornia, home, according to Los Angeles County District Attorney spokeswoman Sandi Gibbons.
