CLAY COUNTY, Fla. (From WFAA-TV) --A Georgia-Pacific facility was locked down Tuesday after a recently fired employee made death threats against the mill before allegedly murdering three people before taking his own life.

Until last week, Murray Lancaster, 40, worked at the Georgia-Pacific Mill in Palatka. A spokesperson would not say why he was fired, but did say he made death threats against the mill. Between 250 to 300 people were at the mill Tuesday while the place was put on lockdown after the earlier triple-murder.

Surveillance footage of an abduction that led to a triple murder in Green Cove Springs was released on Wednesday, less than 24 hours after its conclusion. The video shows Lancaster entering the Keeping It Classy Hair & Nail Saloon and forcing one of his eventual victims into his pickup truck.

That victim, Valorie Short, and her father Welland 'Buddy' Short, were shot and killed near Magnolia Point Golf off Colonial Drive shortly after that footage was recorded, according to police.

Lancaster was later found dead inside a trailer off Idlewild Avenue in Green Cove Springs after shooting and killing Short, her father and Lancaster's ex-wife.

At 9:45 a.m., Lancaster reportedly kidnapped Valorie, his girlfriend, from a nail salon she worked at on Orange Avenue in Green Cove Springs across from the Clay County Courthouse.

He lured Buddy Short to them near Magnolia Point Golf off Colonial Drive. According to Clay County Sheriff Rick Beseler, he shot and killed both Valorie and Buddy Short there.

Then Lancaster drove to the landfill on Rosemary Hill Road and then killed one of his ex-wives, Erica Green. She was at work at the landfill at the time.

Beseler said that after that Lancaster fled to a trailer on his property off Idlewild Avenue where he allegedly shot himself. Investigators said he was likely dead before SWAT surrounded his property.

A manhunt ensued for several hours after the shootings, and eventually authorities found his pickup and rifle they said they believe he used in the shooting, a .223-caliber rifle.

According to a friend, Valorie Short had two children, aged 9 and 7.

In March, Lancaster was arrested for battery and resisting arrest after getting into a fight with Buddy Short at his house. The police report showed that Lancaster was intoxicated and kept yelling obscenities at Buddy Short.

Lancaster has also been arrested for violating a court ordered restraining order against one of his former girlfriends.

Before his death, Lancaster reportedly tried to go to his kids' school to "say good-bye" at Charles Bennett Elementary. His children were not harmed, Beseler said.

Multiple public schools were shut down for the duration of the investigation.
