Wisconsin police on Saturday arrested a second teenager in the murder of a respected doctor and her husband, who were found in a ditch on the University of Wisconsin-Madison campus Tuesday morning.
The University of Wisconsin-Madison Police Department arrested Khari Sanford, 18, early Friday morning and Ali’ja J. Larrue, also 18, late Friday night, charging both with two counts of party to a crime for first degree intentional homicide.
The department also revealed for the first time that Dr. Beth Potter, 52, and her husband, Robin Carre, 57, were shot.
As CrimeOnline previously reported, a jogger discovered Potter and Carre in an outdoor recreational area on the university campus. According to local reports, Potter was still alive when emergency responders arrived at the scene but later died at a hospital. Carre was declared dead at the scene.
UWPD has made a second arrest in the murders of Robin Carre and Beth Potter. UWPD investigators believe the two primary suspects in this murder investigation are in custody.

Police said they believe Sanford, who was known to the couple, and Larrue are the two primary suspects.
“It was calculated, cold-blooded, and senseless — and we will continue to do all we can to bring justice to Robin and Beth, their family, and their loved ones,” said said UWMPD Capt Kristen Roman.

Potter worked at a university-run medical center, and Carre ran an educational consulting business and was also an athletic coach. Police said earlier this week that the pair was targeted and the killing was not random. They have not released the specific cause of death.
This is a developing story and all information is preliminary. CrimeOnline will provide further updates when more information is available.
