FBI: Vegas shooter had 'lengthy' criminal history

LAS VEGAS (AP) - Authorities say a gunman shot dead after killing a Las Vegas federal building security guard and wounding a U.S. marshal had a lengthy criminal history in Tennessee and California, including a conviction for killing his brother.

FBI Special Agent in Charge Kevin Favreau said Tuesday that 66-year-old Johnny Lee Wicks faced murder charges in Memphis, TN, in the mid-1970s, and sex assault charges in Sacramento, CA, in the late-1980s.

Court records show Wicks complained of racial discrimination and lost a federal lawsuit last year challenging a $286 cut in his $974 monthly Social Security benefits after moving from California to Las Vegas.

Wicks also feuded with managers who evicted him from a downtown apartment building for seniors and people with disabilities in Fresno.

The FBI and local police say Wicks torched his apartment and walked three miles to the courthouse before opening fire Monday morning, killing 72-year-old security officer Stanley Cooper.
