PHILADELPHIA (Reuters) - The gunman in a quintuple shooting that left a toddler and one man dead in a possible revenge crime at a Pennsylvania weekend home was "an evil unrepentant monster," a prosecutor said on Tuesday.
Mark Geisenheyner, 51, who was later killed by police after a six-hour standoff at a friend's home, was accused in the Saturday bloodbath at the rural Montgomery County country home of Paul and Monica Shay of New York City.
"Guess you never thought you'd see me again," Geisenheyner told Paul Shay after he broke into their home northwest of Philadelphia where they were entertaining guests over the holiday weekend, according to Montgomery County District Attorney Risa Vetri Ferman.
The violence may have been provoked by an insurance dispute that Geisenheyner had with one of the victims, Vetri Ferman said.
She declined to comment on media reports that Geisenheyner had been imprisoned for receiving a stolen piece of art from the Shay home in 2006 as part of an insurance scam. The reports said when he was released from jail, he sought revenge.
She said it would be inaccurate to say that Shay was a part of any insurance fraud.
"What we've learned from the investigation is that for the past 15 months or so, Mark Geisenheyner had been planning to break into this home, to steal and to kill Paul Shay," Vetri Ferman said at a news conference.
After forcing his way into the Douglass Township home, Geisenheyner killed the homeowner's nephew Joseph Shay, 43, of West Yarmouth, Massachusetts, and New York City and Gregory Bosco, 2, of Fall River, Massachusetts, who was found on a bed, shot in the head.
He also shot and critically wounded the child's mother, Kathryn Lynn Erdmann, 37, and Paul Shay, 64, and his wife Monica Shay, 58. Although gravely injured, Kathryn Erdmann and Paul Shay spoke with investigators.
The gunman fled, heading for the home of a former acquaintance in Trainer, Pennsylvania, about 48 miles south. The next day, after police surrounded the house for hours, Geisenheyner was shot and killed in the basement.
"He is an evil, unrepentant monster," Vetri Ferman told Reuters.
She said Geisenheyner was armed with "at least" two handguns, a .22 caliber and a .45 caliber. The .22 was located later in the Schuylkill River, near the murder scene in Douglass Township.
