Slain Officer Was Lassiter Graduate

The funeral for a first-year Clayton County Police officer killed in the line of duty this week will take place Friday at East Cobb's Johnson Ferry Baptist Church.

Sean Callahan, 24, who joined the force in August, died early Tuesday after being shot twice in the head while responding to a domestic dispute at a motel in Stockbridge on Monday afternoon.

He graduated in 2006 from Lassiter High School, where he was a varsity swimmer, and also attended Mabry Middle School.

A Lassiter guidance counselor told The Marietta Daily Journal that Callahan expressed to her an interest in studying criminal justice. According to The Atlanta Journal Constitution, Callahan paid his own way to Reinhardt University's Police Academy and graduated in June 2011.

Friday's funeral will take place at 11 a.m. A visitation on Thursday is scheduled from 6 p.m. to 9 p.m. at Pineride Memorial Park, 2950 N. Cobb Parkway in Kennesaw.

Callahan is the first Clayton officer to die in the line of duty in the department's 84-year history, according to Clayton Police Chief Gregory Porter.

The man who allegedly killed Callahan was shot and killed by police during the Monday incident. According to the Clayton News-Daily, Tremaine Lebis served 15 years in prison for aggravated assault and firearms convictions, and last year served several months in jail for possessing a firearm by a convicted felon.

Lebis' wife Lisa Ann Lebis was charged with simple battery of a police officer and obstruction of an officer, according to the newspaper.

In an interview Tuesday night with 11 Alive, Candice Shirley, Callahan's sister, said their mother feared for his safety as he embarked upon his law enforcement career.

"From the moment he was hired, fear was automatically in her heart, and she would cry some nights just talking to me about it," Shirley said of Darlene Callahan, whose husband died when Officer Callahan was in high school.

"At the end of the day, my brother is a hero," Shirley told the television station.
