A wedding story:

A Hells Angels widow showed up at a West Philadelphia church before a biker wedding on Saturday and yelled at rival Pagans for killing her husband last January, according to authorities.

The widow, Margie Wood, once a friend of the marrying couple, left the scene without further incident, authorities said.

Meantime, the groom, Dominick “Tack” DiPietro, 42, and his Philly chapter president, Steven “Gorilla” Monde-vergine, led a roaring pack of Pagans on their Harleys along the Schuylkill Expressway, where a banner hung on the South Street bridge that read:

“Congratulations to Tack and Maria” and “Death to the Hells Angels.”

The Pagans then rode past the Angels’ block party on Merion Avenue near Girard, en route to the wedding at Our Lady of Angels Church, 50th and Master streets, in West Philadelphia.

Philadelphia police and FBI agents removed the banner 20 minutes after it was put up and monitored both the block party and wedding, which were two blocks apart.

A law-enforcement official said there were no incidents.

Despite the biker rivalry, the widow, Margie Wood, and the bride, Maria Sinagoga-DiPietro, 41, had been “good friends, until the murder,” said the new bride. “Once [Thinker] got killed, she was bitter toward the Pagans.”

Early on Jan. 14, then-acting Angels president Thomas “Thinker” Wood, 36, was gunned down in his truck on the Schuylkill Expressway near Vare Avenue.

The unsolved murder is under investigation by a federal grand jury and Philadelphia homicide detectives.

“I still love her to death,” said Sinagoga-DiPietro. She’s a great person, a great mother, and I know she’s suffering. I miss her, I do.”

Wood, a petite woman dressed in jean shorts and a white tank top, attended the Angels’ party.

She was asked not to talk with a reporter by “Slim,” believed to be James “Slim Jim” Wysong, one of the four former Pagans who patched over to the Angels. Wysong was briefly president of the Philadelphia chapter.

“Margie is good people,” said the groom, “but Thinker, he shakes my hand and gives me a kiss and is plotting to turn the Philly Pagans into the Angels.”

“I sponsored Thinker when he came into the Pagans and then he betrayed me,” said DiPietro, who wore a ponytail with a Pagan vest over his black tuxedo at the reception.

“He went to the Hells Angels, and I went to jail.”
