Two more people have been arrested on charges related to the killing of two Hattiesburg police officers.

The Mississippi Bureau of Investigation on Friday charged 21-year-old Douglas McPhail and 19-year-old Anquanette Alexander with obstruction of justice for actions investigators say they took after the shootings to help people involved. Both are held in Forrest County Jail awaiting court appearances. It's unknown whether either has an attorney.

Seven arrests have been made in the Saturday shootings of officers Benjamin Deen and Liquori Tate.

MBI spokesman Warren Strain says bond was set at $75,000 Friday for Abram "Pete" Franklin, arrested Wednesday for obstruction of justice.

Marvin Banks is jailed without bond on two capital murder charges. His girlfriend, Joanie Calloway; younger brother, Curtis Banks; and a friend, Cornelius Clark, also face charges.
