Globetrotting Ex-SpaceX Rocket Scientist Arrested for Alleged Murder of Wife in Maine After Couple Traveled North America, Sailed French Polynesia

The 34-year-old man charged with allegedly murdering his wife in Readfield on Wednesday is a former SpaceX engineer who traveled the globe extensively with his now-deceased partner, a French woman who documented the luxurious trip on social media before the pair moved back to Maine.

Maine State Police were called Wednesday to the Giles Road residence of Dorothy Whittemore, 67, and arrived to find 32-year-old Margaux Whittemore, née Margaux Nguyen, deceased in the driveway, also unclothed.

Police took into custody Samuel Whittemore of Belfast, Dorothy’s son and Margaux’s husband, who had fled the scene.

According to a press release from Maine State Police spokesperson Shannon Moss, the suspect’s mother was found at the residence suffering from injuries and later hospitalized in Lewiston. She is in stable condition.

Samuel Whittemore was briefly taken to Maine General Hospital in Augusta for a medical evaluation before being taken to Kennebec County Jail and charged with murder.

Margaux and Samuel had recently moved back to Maine and were living in Belfast.

According to his LinkedIn profile, Whittemore is a 2014 graduate of the Massachusetts Institute of Technology who worked as a Senior Avionics Systems Engineer at SpaceX until 2021.

The profile also describes him as the captain of the Havili, a 50-foot sailboat which he sailed across the Pacific, “with stops in Mexico, French Polynesia, Tonga, New Zealand, [and] Hawaii.”

Prior to Whittemore’s alleged homicidal outburst, the young couples’ life story played out across Instagram in dreamlike fashion, with the pair exploring the world together by land and by sea — the modern equivalent of a story book romance and life story.

According to Margaux’s social media posts, the pair met in 2021 and wed in Acadia National Park in September of last year.

Police have yet to release a motive.
