The Millington Police Department is investigating the deaths as a murder-suicide.
According to family members, Amy Lange and her estranged husband, Mark Perry, were found dead at a home located on the 3000 block of Oakhurst Avenue.
Lange was highly regarded as a Shelby County Schools teacher. She was previously honored as MCHS Teacher of the Year, as well as SCS Teacher of the Year.
"She has this uncanny ability to pull out the creative side of students," Millington Central High School Principal Mark Neal said in a video done about Lange when she was honored as Teacher of the Year.
