I don't know about a ping list, but I do know that this important issue was first investigated by the intrepid Chuck Shepard, in his syndicated "News of the Weird" column. From 1996:
An increasing number of vicious criminals with the middle name of Wayne made the news in 1996. For example, Conan Wayne Hale, 20, a triple-homicide suspect who allegedly confessed to a priest in Portland, Ore., was embroiled in a constitutional court fight to have the confession ruled inadmissible. Escaped murderer Michael Wayne Thompson was recaptured in July near Farmersburg, Ind. A few days later, Danny Wayne Owens, 38, was arrested in Birmingham, Ala., for allegedly murdering a neighbor. In November, Georgia executed Ellis Wayne Felker for the 1981 murder of a college student. Also in November, the suspected rapist of a 12-year-old girl in Petaluma, Calif. (two miles from where Polly Klaas was abducted in 1993), Larry Wayne Cole, apparently died of natural causes while on the lam. And in October, the Oregon Parole Board turned down the latest bid by Richard Wayne Godwin, serving a life sentence for a 1979 rape and murder.

In September 1996, News of the Weird listed an array of vicious criminals who happened to have the middle name Wayne.

And in October, the Oregon Parole Board turned down the latest bid by Richard Wayne Godwin, serving a life sentence for the 1979 rape and murder of a 5-year-old girl.
Still more:
The Classic Middle Name: Conan Wayne Hale, 20, a triple-homicide suspect who allegedly confessed to a priest in Portland, Ore., has been fighting for three months now to have the confession ruled inadmissible in court on freedom of religion grounds. And escaped murderer Michael Wayne Thompson was recaptured in July near Farmersburg, Ind. And a few days later, Danny Wayne Owens, 38, was arrested in Birmingham, Ala., for allegedly murdering a neighbor. (Among other prominent middle-name Waynes: serial killers John Wayne Gacy of Illinois and Elmer Wayne Henley of Texas; recently executed Arizona murderer Jimmy Wayne Jeffers; sadistic Louisiana murderer Robert Wayne Sawyer; the Ohio Aryan Nations member caught last year with freeze-dried bubonic plague bacteria, Larry Wayne Harris; the Oklahoma rapist recently sentenced to 21,000 years in prison, Allan Wayne McLaurin; and of course John Wayne Bobbitt.)
And still more - a recent set from March of this year:
Arrested for murder: Christopher Wayne Davis (Pearl River, La., November), Jerry Wayne Dean (Jackson County, Ky., November), Billy Wayne Cope (Rock Hill, S.C., November), Joshua Wayne Andrews (Woodbridge, Va., January), Jeffrey Wayne Gorton (Flint, Mich., February), Timothy Wayne Adams (Houston, February). Murder Warrant Issued: Jason Wayne Johnson (Comal County, Texas, December). Sentenced for Murder: Mark Wayne Campmire (Litchfield, Conn., January). Executed for Murder: Randall Wayne Hafdahl (Huntsville, Texas, January), Stephen Wayne Anderson (San Quentin, Calif., January). Avoided a Murder Charge Only Because He Was Killed in a Shootout With Police: Danny Wayne Sand (Brandon, Manitoba, December). Appealed or Sought Parole: convicted murderers Kenneth Wayne Woodfin (Richmond, Va., January), Gary Wayne Sutton (Knoxville, Tenn., January).
In fact, as of June, 2001, Mr. Shepard had compiled an honor roll of all those appearing in his column between 1996 and mid-2001, with the classic evil middle name, which you can read here.
As for this particular waste of life, I can only hope that he had no transmissible disease that he might have infected his victims with, and that he is prosecuted to the fullest extent of the law...
"Speaking of E's, the second listing is for Earl. Nothing against the name Earl (there is Earl Campbell, Earl Warren, Steve Earle, Earl Klugh, Earl "The Pearl" Monroe and the Duke-Duke-Duke, Duke of Earl), but you want to avoid putting Earl with Wayne. Ever notice how many killers are named Earl Wayne or Wayne Earl Something?"
