He pleaded guilty to two counts each of burglary and criminal conspiracy and was sentenced to three to eight years. Charges including criminal trespass, receiving stolen property and possession of an instrument of crime were dropped in exchange for his pleas.
Goffney, 27, could have faced up to 40 years in prison if convicted after trial.
"Thank you for your lenience in accepting my plea," Goffney, of Pennsauken, N.J., told a judge in court Wednesday. "These crimes won't be happening again."
Goffney's twin brother, Keyontyli Goffney, also is charged and appeared at Wednesday's hearing, but it was unclear if he planned to negotiate a plea. He's due back in court Aug. 6. Neither his lawyer, Gerald Stein, nor Assistant District Attorney Caroline Keating immediately returned telephone calls from The Associated Press on Thursday.
Keating told the Philadelphia Daily News that Taleon Goffney is sure to serve at least the minimum three years due to his prior criminal record. Goffney's lawyer, Michael F. Gushue, told the newspaper that his client plans to complete his college education while in prison.
"I think he's had an epiphany," Gushue said. "He's a bright young man."
The brothers have appeared in Internet porn videos under the names Teyon and Keyon, said Erik Schut, of Philadelphia-based video retailer TLA Entertainment Group. They could have had good careers if they hadn't gotten into trouble, he said in February.
"They are incredibly good-looking, and being identical twins, it's a novelty," Schut said then.
In "Marc and the Twins," the brothers offer to audition for chiseled porn star Marc Williams in a seedy hotel room and are seen rubbing each other's chests.
Keyontyli Goffney has appeared in porn since at least 2002 and worked as a fashion model, while Taleon Goffney got involved in porn more recently.
Taleon Goffney, who police believe is a trained gymnast and karate expert, has used his athleticism to make several daring escapes.
He was handcuffed in the back of a moving police cruiser after a 2006 drug arrest in Clementon, N.J., when he broke out the glass with his head and jumped into a lake while still handcuffed, police Chief Dave Kunkel said.
"He swam across like Flipper, taunting the officers, saying, 'You'll never catch me,"' Kunkel told the Daily News for a story in February.
He turned himself in a week later.
In January 2007, he jumped 30 feet from the roof of a Camden, N.J., liquor store and swam across the frigid Cooper River before he was caught, police said.
A defense lawyer, Jeffrey Zucker, said Goffney "should have signed up for the Olympics" and referred to him as Spider-Man.
