 The city of Cleveland mourning the death of a police officer killed in the line of duty. Officers were attempting to serve an arrest warrant overnight when they came under fire. A 27-year-old officer was hit by that gunfire and died. Cleveland Police Chief Fannie Todd. I ask the community to keep our law enforcement members, men and women, in their prayers. This is a really tough situation and it's hitting everyone really hard. A 24-year-old suspect in custody charged with aggravated murder in the case.
