Wisconsin authorities arrested and charged a teenage girl in what they called the “calculated” double murder of a college doctor and her husband last week, police said on Saturday.
Police at the University of Wisconsin-Madison said that 18-year-old Ali’jah J. Larrue was convicted of two counts of first degree intentional homicide in the murders of Dr. Beth Potter and Robin Carre.
The announcement of Larrue’s arrest came a day after police said an alleged accomplice, 18-year-old Khari Sanford, had also been placed in police custody on suspicion of being a party to the murders of Potter and Square.
A jogger found the bodies of Potter, 52, and Carre, 57, in a ditch early Tuesday morning at the University of Wisconsin Arboretum, an ecological research center with more than a dozen kilometers of trails.

Carré was pronounced dead at the scene. Potter later died in a local hospital.
Police said Sanford was “known” to the families of the victims and that their murders appeared to be targeted.
“We think it was not a random act,” the authorities said in a statement. “He was calculated, cold-blooded and insane – and we will continue to do everything we can to do justice to Robin and Beth, their families and loved ones.”
The NBC WTMV affiliate reported that Sanford attended the same high school as the couple’s daughter.
In a statement, the University of Wisconsin said Potter was an associate professor in the Department of Family Medicine and Community Health. She has pioneered occupational health and chronic pain programs and has taught and mentored hundreds of family medicine students.
“She was wise, warm and always supportive,” said colleague William Schwab. “There are so many people in our department whose lives have been touched by Beth; its loss will weigh heavily on us. “
Carre was an independent educational consultant and football coach, according to his website.
Larrue and Sanford are scheduled to appear in court next week, the Associated Press reported. It is not immediately known if they have lawyers.
