LOUISVILLE, Ky. (WDRB) -- The man accused of killing three people in south Louisville made his first court appearance Monday.

George Slaughter is charged with three counts of murder and tampering with physical evidence. The 26-year-old  is being held at Metro Corrections on $1 million cash bond.

Police say he shot and killed 36-year-old Douglas Weber, 35-year-old William Neal, and 43-year-old Elizabeth Draper early Saturday morning at a home on Wheeler Avenue. 

Draper and Neal lived at the home; Weber was from New Albany. 

Investigators believe Slaughter acted alone and do not expect to arrest anyone else. Police have not disclosed a motive.

WDRB has confirmed that Slaughter was also charged with murder in 2007.

He was sentenced on charges of manslaughter in the second degree and robbery in the second degree.

Slaughter was 17-years-old when he shot and killed 18-year-old Bobby Sweatt in Louisville in 2007.

Slaughter was sentenced to serve 10 years behind bars but was released from custody in 2012.

WDRB.com reporter, Jason Riley, explains it is not uncommon for a person to be released before their sentence is up.

"He was released properly, he was released on a program that the state has been using since 2011, and there is no indication that he should have been in prison at the time this occurred,” said Riley.

Slaughter pleaded not guilty. He remains jailed on a $1 million cash bond.
