We now know the chilling details of that December night when two Topeka police officers were killed in the line of duty.
Five seconds - that's all it took to end the lives of Topeka's Corporal David Gogian and Officer Jeff Atherly.
At a press conference Wednesday morning, Shawnee County District Attorney Chad Taylor shares his complete investigation of the night he says 22-year-old David Tiscareno killed two of Topeka's finest.
"On Sunday, December the 16th, 2012, at 6:08 p.m. the call came into the dispatch center from a security guard working at Dillon's at Huntoon and Washburn," Taylor says.
Taylor says Corporal Gogian was first on the scene after the call about a suspicious vehicle. He then called for backup and officer Atherly arrived. Gogian asked a woman in the driver's seat and Tiscareno, in the back seat, to get out of the car. Taylor says Tiscareno responded with gunfire and shot Officer Atherly in the head.
"He then swung the gun towards Corporal Gogian and TPD officer 3," Taylor says. "Tiscareno then fired two more rounds, one striking Corporal Gogian the head from approximately four feet away."
Tiscareno left the scene in his car. Hours later, Federal, State and local law enforcement tracked him down at 306 S.W. Western. A standoff turned into more gunfire and Tiscareno died from at least three gunshot wounds.
"My understanding was that he was out on warrant at the time that this event took place and was the subject of other ongoing investigations," Taylor says.
He adds that Tiscareno had drugs in his system that night.
"The subject had a substantial amt of methamphetamine on board," Taylor says.
But what's most disturbing, Taylor says, is the Facebook post Tiscareno wrote just 48 hours before the tragedy.
"I'm a dead man walking, I'll kill you, I'll kill myself," Taylor reads, "Lost everything that made me happy, now I'm heartless and emotionless. I'm lost with the wicked, nobody's safe. Go ahead and try to get me, coppers, got bullets for everybody and me, death is all around me."
A frightening premonition of the events that unfolded just two days later, when two futures were shattered.
Taylor says Tiscareno acted alone that night, even though there were three women with him at the time. Taylor doesn't have a suspected motive that led Tiscareno to shoot Corporal Gogian and Officer Atherly.
Shawnee County's investigation is now closed.
