Killer in the House: Ten Days of Terror in a Pennsylvania Suburb

by Kathryn Canavan

A gripping, meticulously researched account reconstructing the minute-by-minute murders of six victims in 1976 Pennsylvania.

A meticulously researched page-turner about one of the Philadelphia suburbs’ most shocking 20th-century crimes. A gunman broke into Jack and Peggy Abt’s house moments after the last family member left for the day. He took a seat next to the upright piano in the living room and waited silently for 11 hours. He didn’t eat. He didn’t sleep. He didn’t watch television.

People expect things to go bump in the night, but, in 1976, most adults never fretted a stranger would invade the sanctity of their home in the middle of the day. Six people walked through the kitchen door one by one that afternoon, all expecting nothing more than a Friday night fish fry. The killer leaped out from behind the living room wall over and over and over and over and over and over again. He fired at them at a distance of less than 18 inches, the width of a dining room chair. After each murder, he dragged the body to the basement. Then, to maintain the element of surprise, he sped back upstairs to tidy up for his next unsuspecting victim.

This first-person story from a news reporter who was on the scene 90 minutes after the killer slipped away is built from autopsy reports, prison records, IQ tests, trial transcripts, the killer’s own eidetic confession, interviews with witnesses in 1976 and in the 2020s, and the author’s experiences covering the case from the first night to the stunning courtroom moment when the announcement of six death penalties was met with loud cheers.

With that research, it was possible to reconstruct the six murders, minute by minute. Tension builds as the six innocent victims turn the kitchen doorknob at 3:30, 4:15, 4:40, 5:15, 6:10 and at 6:30. Readers know their fates, but they didn’t.

Anyone interested in true crime stories should read this book. Kathryn tells the story from a unique perspective of a young reporter with first hand knowledge of these events, but she also helps us see the story from the perspective of the others who were there, the neighbors, police officers, friends, the survivors. And considering it was 1976, with no cell phones, no internet, it's hard for younger people to understand just how amazing it was that the detectives closed this case in 10 days. I couldn't put it down.

I was 13 in 1976, in 8th grade, attending the same middle school as Kathy and John. I didn't know them well, but I had friends who did, including my younger brother who was friends with John and one of my classmates who is mentioned in the book. I can still remember my friends and I being in shock and none of us wanting to go to school on Monday. If you remember, you should read this book, I found out so many facts I never knew.

"Killer in the House" is a gripping, meticulously researched account of the horrific 1976 murder of a family in suburban Philadelphia. What sets this book apart is the author’s unique vantage point; Canavan was a young reporter covering the case as it unfolded. The author transports you to the street where the crimes occurred, making you feel like you know the Abt family, their neighbors, and the investigators on the case. I especially appreciate the inclusion of details that, while not always directly tied to the crime, paint a fascinating picture of the 1970s world. Though the story of what happened on that day is unimaginably grim, Canavan balances the darkness with a deeply humanizing voice, occasionally even using humor to ease the heavy subject matter. Many chapters were suspenseful—especially as Canavan recounts her own high-stakes experiences as a reporter on the scene. To think of where technology is today and how these investigators had none of that to their advantage yet solved the case is incredibly impressive. As an avid true crime reader, I highly recommend this haunting story of one of the region’s most notorious crimes.

*I received an advanced copy of this book through Brookline Books.*

Very well written and reminiscent of the late true crime writer, Ann Rule and how she wrote with such great passion and attention to detail. I am very familiar with the Abt family murders as I was 14 when this happened and lived less than three miles from the house where the horrific murders took place. This book took me back in time as the author captured every finite detail about the neighborhood and how life was in Lower Bucks County, PA in 1976. I don’t remember the Vogenbergers murders at all, though as that was in a neighboring township and living in the same township as the Abt murders, I heard about that with great detail. I didn’t know the kids as my age was in between the younger and older Abts. The photo of Kathy Abt gives me chills as I remember seeing it in the local paper back then. I am planning to go to a book signing by the author soon and hope I get a chance to tell her how she did justice to this true crime.

True Crime in Philadelphia Suburb

Riveting story that happened in a quiet community outside Northeast Philadelphia in 1976. Amazing work by the police at a time when today’s technology did not exist to help in their investigation. Crime was solved in 10 days.
