OJ Simpson is making a rare public appearance at a Hallowe'enthemed comic book convention, which coincides with the 10th anniversary of his acquittal on murder charges,

The former American football player has agreed to put in a three-day appearance at Los Angeles' NecroComicon show, which started yesterday (30SEP05), as a favour to a pal.

Promoter TOM RICCIO insists Simpson is "not getting a penny" for his visit, but is using the event as a possible trial run for future public appearances which he'll make "in exchange for donations to his kids' college fund".

Riccio says, "A lot of promoters are watching this to see how it goes, and we're going to take it from there." Riccio plans to charge $95 (GBP52) for photographs and T-shirts signed by Simpson, and $125 (GBP69) for autographed football jerseys and helmets.

Tomorrow (02OCT05), Simpson will be joined at the event by his old friend and former football teammate AL COWLINGS, who drove his pal around Los Angeles during the televised police pursuit that ended with Simpson's arrest at his home on murder charges.

Monday (03OCT05) marks 10 years since a California jury found Simpson not guilty of murder in the June 1994 slashing and stabbing deaths of his ex-wife, NICOLE BROWN SIMPSON, and her friend, RONALD GOLDMAN.

In 1997, a civil court jury found Simpson liable for the deaths and ordered him to pay $33.5 million (GBP18.6 million) in damages to the families of the victims.
