The DeKalb County teacher charged in the shooting deaths of two young children at a home in Clayton County in 2016 is expected in court on Tuesday.

Michael De'Sean White was arrested on March 23 and charged in connection with the deaths of 15 year-old Daveon Coates and his 11-year-old sister, Tatiyana, during a violent home invasion on October 22, 2016.

Daveon and Tatiyana were inside their home with a number of children when the suspects came in. Their parents were reportedly socializing at another location at the time of the incident.

Shortly after the shootings occurred, the Clayton County Police Department told CBS46 that the victims' mother had opened up her home to another woman and her five children, who had moved to metro Atlanta from Tennessee. Police say one of those kids staying at the home, an unidentified 15-year-old, was involved in gang activity.

During a press conference in late March, Clayton County Police Chief Kevin Roberts said the juvenile had stolen weapons from several gang members in DeKalb County, and in retaliation, those gang members came to the home in Jonesboro and fatally shot Daveon and Tatiyana.

Police were able to gain information on the case after the juvenile was involved in a drive-by shooting in Chattanooga, Tennessee. A gun was dropped on the scene, and after months of investigating, police were able to connect that weapon to the shooting in Jonesboro.

Clayton County Police Captain Stehan Schindler says he can't believe that someone trusted in teaching children stands accused of such a crime.

"We were absolutely flabbergasted to come to the realization that a fifth-grade teacher who is teaching children is part of this," said Schindler.

In all, 11 people have been charged in the case, nine of which are facing murder charges.

White is expected to appear in court at 8 a.m.
