BILOXI, Miss. – The Latest on the funeral of a police officer killed in Mississippi (all times local):

3:35 p.m.

One of Mississippi's top elected officials says a police officer killed on duty was "a man of integrity" who protected others.

Republican Lt. Gov. Tate Reeves spoke Monday at the funeral of Biloxi Patrolman Robert McKeithen (muh-KEETH-en). The 57-year-old officer was shot to death May 5 outside the Biloxi police station.

Hundreds of law enforcement officers joined other mourners at First Baptist Church in Biloxi.

McKeithen's supervisor, Lt. Thomas Goldsworthy, said McKeithen was known for his smile and many nicknames, including "Old Man" and "Pop Pop." McKeithen enjoyed 3 a.m. breakfasts at Waffle House, and waitresses there personalized a coffee cup for him by writing "Robocop" on it.

Investigators have charged 19-year-old Darian Atkinson with capital murder in McKeithen's death. Atkinson's brother and three others are charged as accessories after the fact.
