Black Marine accused of torturing and murdering his commanding officer and his wife began urinating during his court hearing

Kesuan Sykes, whose nickname is "Psycho," was in the midst of a pre-trial hearing when he stood up and began flinging urine around a California courtroom. Court officers pounced on the shackled suspect, and the judge ordered Sykes to undergo a mental evaluation after the disgusting display. Sykes, 23, is believed to be the most disturbed of the four Marines charged with the brutal murders of Sgt. Jan Pawel Pietrzak and his wife, Quiana. Sykes allegedly joked about sodomizing Quiana Pietrzak with a sex toy - in front of her hog-tied husband - and made "buzzing sounds," a detective has testified. Pietrzak, 24, a Polish immigrant who grew up in Bensonhurst, and his 26-year-old wife were killed after the intruders burst into their Riverside County home. Tyrone Miller and Kevin Cox, both 23, and 21-year-old Emrys John are also charged with murdering the newlyweds during the robbery. The sadistic fiends discussed burning the Pietrzaks alive, but couldn't light a shirt on fire on the stove, police said. So they shot them both in the head. Cops later found stolen jewelry, an ATM card and Pietrzak's dress uniform in the accused Marines' rooms at the Camp Pendleton military base.
