A second suspect was arrested late Friday in the double homicide of Dr. Beth Potter and her husband, Robin Carre, whom UW Police believe were shot by the pair of 18-year-old men.
Ali’jah J. Larrue was arrested at about 11:20 p.m. and booked into the Dane County Jail on two tentative counts of being a party to the crime of first-degree intentional homicide, police said.
Earlier Friday, Khari Sanford was arrested on the same tentative charges.
Potter, 52, and Carre, 57, were found at 6:30 a.m. Friday by a jogger who saw them lying in a ditch about a quarter of a mile into the UW Arboretum from the entrance on North Wingra Drive. Carre died at the scene, and Potter was taken to a hospital where she died shortly afterward.
Early Saturday afternoon, two UW police officers and a search dog were looking for evidence along North Wingra Drive.
Sanford “is known to the family” of Potter and Carre, UW Police Chief Kristen Roman said Friday, but she did not elaborate on the nature of the relationship.
On Saturday, police spokesman Marc Lovicott declined to specify how investigators connected Larrue and Sanford to the killings.
“It’s an intense investigation of a serious crime,” he said. “There are lots of pieces to the puzzle. Using information from the community, we were able to put these two in custody — and we do believe these are the two primary suspects.”
Police also didn’t say how Larrue and Sanford know each other, though Larrue indicated on Facebook that he had attended West High School, and Sanford was on the roster as a receiver for the school’s football team last fall.
The pair are pictured among several other young men in a Facebook post dated March 31 of last year.
Lovicott said, “I don’t know what their relationship is beyond” being suspects in the homicides.
“While this remains a very active police investigation, UWPD investigators believe the two primary suspects in this murder investigation are in custody,” police said in a statement. “We believe this senseless and tragic act was targeted towards the couple and was not random.”
Potter was a family medicine physician at the Wingra Family Medical Center, run by the UW-Madison Department of Family Medicine and Community Health and Access Community Health Centers. Carre, an educator and former coaching director of Regent Soccer Club, offered consulting services to students and their families for the college search and application process.
