full_context: Document 1: William Bonin: William George Bonin (January 8, 1947 – February 23, 1996) was an American serial killer and twice-paroled sex offender, also known as the Freeway Killer, who committed the rape, torture and murder of a minimum of 21 boys and young men in a series of killings in 1979 and 1980 in southern California.

Document 2: Texarkana Moonlight Murders: The Texarkana Moonlight Murders, a term coined by the news media, references the unsolved murders committed in and around Texarkana in the spring of 1946 by an unidentified serial killer known as the "Phantom Killer", or "Phantom Slayer". The killer is credited with attacking eight people within ten weeks, five of whom were killed. The attacks happened on weekends between February 22, 1946 and May 3, 1946. The first two victims, Jimmy Hollis and Mary Larey, survived. Some police officers are not sure if their attack was connected with the murders. The first double murder, which involved Richard Griffin and Polly Ann Moore, happened four weeks later. The second double-homicide, involving Paul Martin and Betty Jo Booker, occurred exactly three weeks from the first murders. The Texas Rangers came in to investigate, including the famous M. T. "Lone Wolf" Gonzaullas. Finally, almost exactly three weeks later, Virgil Starks was killed and his wife, Katie, was severely wounded. Most officials no longer connect that attack to the other murders. Contrary to popular belief, the killer did not attack during a full moon, but did strike late at night.

Their exploits captured the attention of the American public during the "Public Enemy Era," between 1931 and 1935. Though known today for their dozen-or-so bank robberies, the duo most often preferred to rob small stores or rural gas stations. The gang is believed to have killed at least nine police officers and several civilians. The couple was eventually ambushed and killed by law officers near Sailes, Bienville Parish, Louisiana.
