South Carolina authorities have arrested a suspect in connection to the fatal Sunday shooting of an elementary school principal.

Dillon County deputies on Sunday responded to reports of a shooting on the 1800 block of Southwind Road and found Wendy Cook, 54, shot dead in a car and the suspect, Kyle Church, 31, still sitting in the same vehicle, according to authorities and local reports.

"I am saddened by the passing of Dr. Wendy Cook, principal of Stewart Heights Elementary School. Her colleagues and friends in Dillon County School District 4 talk about the great work she did leading her school and many of the impacts she had on her students and staff," South Carolina Department of Education Superintendent Molly Spearman said in a Monday statement.

Spearman added that her "deepest condolences are with the entire Dillon school community as they grieve this loss."
