ORIGINAL STORY: Officials on Thursday increased a reward to $70,000 for information leading to the arrest of a man accused of killing one officer and critically injuring another.
Since the deadly shooting Wednesday in Americus, officials have urged Minquell Kennedy Lembrick, 32, to surrender.
“Enough violence has occurred today,” GBI director Vernon Keenan said hours after the shooting. “We want you to call 911 and turn yourself in.”
Lembrick has been on the run since about 10 a.m. Wednesday when Americus officer Nicholas Ryan Smarr, 25, responded to a domestic call at the Country Club Estates apartments on South Lee Street.
Georgia Southwestern State University police officer Jody Smith was called to assist Smarr.
The three exchanged gunfire, but it is not known if Lembrick was struck, Americus police Chief Mark Scott said.
The two officers were shot and sustained head wounds during the gunfire, Channel 2 Action News reported. Smarr died shortly after. His body will be taken to Macon for an autopsy, GBI officials said.
Smith was flown to a Macon hospital and was last reported in critical condition. His status was unknown early Thursday.
“It’s a tragedy beyond words,” Scott said.
Lembrick has arrests and charges dating as far back as 2003.
Lembrick was charged with false imprisonment, simple battery and criminal trespassing in Sumter County, according to the Georgia Department of Corrections website.
At the time of the shooting, Lembrick was wanted on kidnapping and other charges. Officials were not aware of the warrant until after the shooting, Scott said.
“We’d like to express our deepest sympathies to the families and the friends” of the officers, Scott said.
