Maguire, 24, a Harley-Davidson mechanic, tracked him down by calling the Delaware County SPCA.
"He doesn't really have a neck, so he never had tags," he said.
The SPCA said that Ridley police had a pig in custody, so Maguire and his girlfriend, Bernadette Broadhurst, figured that they'd head over to the station to pick him up.
But instead of reuniting Maguire and Broadhurst with their beloved pet, township officials refused to turn him over, citing an ordinance that prohibits farm animals in Ridley.
OK, fine. The couple planned to give Steve to a friend in a more pig-friendly town. Nope. They were told that their $424 pet had been whisked away to an undisclosed location.
Police have since refused to reveal Steve's whereabouts, other than that it's a farm near Reading.
"They said they had put the pig up for 'adoption.' You can't do that. That's my pet! I have the paperwork," Maguire said yesterday. "They won't give me an address, phone number, the name of the farm, anything."
Steve is smart, Broadhurst said, but might not take to life on the farm. They bought him last month at We Love Pets, a local pet shop. He uses a litter box.
"That took no time at all to train him," she said. "He just kind of does his own thing. Dogs bark at the mailman, but a pig just wouldn't even bother with him."
The problem is that Steve isn't really the outdoorsy type, preferring to curl up on the floor with "Hank," their Labrador-hound mix.
"He's a domesticated animal, not a farm animal," Broadhurst said. "We feed him. He doesn't know how to forage on his own."
"And he has dry skin," she added. "He needs lotion."
Will this anonymous farmer take time out of his day to slather Aveeno on a potbellied pig like she did? Broadhurst has her doubts.
But back to the question at hand: Where exactly is Steve?
"I'm not going to comment on it," said Ridley Township Commissioner Michael McCrea, citing the possibility that Maguire could sue.
Maguire said he has contacted a lawyer because he doesn't know what else to do.
A friend began printing "Where's Steve?" T-shirts, and the proceeds will be used to defray any legal expenses accrued in trying to rescue the pig. The shirts are available through the "Where's Steve? Give him back Ridley" Facebook page.
Ridley Detective Lt. Scott Willoughby did not return phone calls or an email from the Daily News yesterday.
"He said, 'He's on a farm. Don't worry about where it is,' " Maguire said, recalling his conversation with Willoughby.
Broadhurst didn't start calling Willoughby a pig or anything, but things did get a little heated. The police report said she needed to get a particular permit to keep Steve, but she later discovered it covered birds, not pigs.
"When I went to the township building, they looked at me like I had four heads when I asked for the permit," she said. "The whole thing is ridiculous."
But it's not ridiculous to have a micro pig for a pet, Maguire insists.
"George Clooney has one. Paris Hilton has one. A lot of people have them," he said. "They are customary pets. It's not that crazy."
They understand Ridley's strict anti-pig ordinance, even if they don't agree with it. But they'd like to give Steve to a trusted friend. More than 50 friends have offered to adopt him.
"I don't think I'm in the wrong," Maguire said. "I just want my pet."
