I'm glad you brought up MacDonald. I've been trying to study all of these family annihilators and write a short summary for each. I know many posters don't have time to read long, drawn-out posts, so I'm trying to keep the summaries short, and boy was that ever hard with this one. The similarities are uncanny, down to his grinning for the camera.
In high school, Jeffrey MacDonald was voted both "most popular" and "most likely to succeed,” he was Senior Class President, captain of the football team and won a scholarship to Princeton. After three years at Princeton, he attended and graduated from Northwestern University Medical School, joined the Army where he held the rank of Captain and was assigned as a Group Surgeon.
In February 1970, he violently murdered his wife Colette, his five-year-old daughter, Kimberly, and two-year-old daughter, Kristen. Colette was pregnant with her third child (a son) and had been stabbed 21 times with an ice pick, 16 times with a knife, repeatedly clubbed, and both her arms were broken. Kimberly was also clubbed, and stabbed in the neck eight to ten times. Kristen was stabbed 33 times with a knife and 15 times with an ice pick.
MacDonald claimed that he was awakened by Colette and Kimberly's screams, went to their aid, and was attacked by three male intruders, and a female with long blonde hair, wearing high heeled boots and a white floppy hat partially covering her face who stood nearby with a lighted candle and chanted, "Acid is groovy, kill the pigs." In other words, “the hippies did it.”
Similar to this case, there were no prior reports of domestic violence. And, MacDonald also made media appearances; most notably on The Dick Cavett Show, where he made jokes and complained that the focus of the investigation was on him. This is a clip from the show where he is seen grinning like a Cheshire cat.
