Caleb McGillivary is being held in the Union County jail in Elizabeth Thursday after he waived extradition following his arrest in Philadelphia on May 16.
The 24-year-old is charged with beating 73-year-old lawyer Joseph Galfy to death after they met in New York City earlier this month. Galfy's partially clad body was found in his Clark, N.J., home two days later.
McGillivary gained Internet fame in February when he was interviewed after he intervened with a hatchet in an apparently unprovoked attack on a Fresno, Calif., utility worker.
McGillivary said he was from Sophia, W.Va., but his father told The Associated Press that McGillivary was born and raised in Canada.
