Prosecutors have released hundreds of pages of documents related to the arrest of the suspect in the bizarre, 28-year-old so-called "killer clown case."
Among the newly uncovered information is the allegation that suspect Sheila Keen-Warren has been linked to the crime through DNA evidence.
Investigators also say that two nights before the fatal May 1990 shooting of Marlene Warren, a customer showed up at a costume shop near the victim's home and begged clerks to let her in at closing time, according to CBS News.
Investigators reportedly say two clerks from the store were told by the female customer that she needed a clown suit, an orange wig, white gloves, a red nose and enough white makeup to cover her face.
One of the clerks identified the customer as Sheila Keen, while another was less sure and said it could have been her, according to the documents.
Also revealed are investigator accounts that Marlene Warren was shot in the lip as she answered her door.
Palm Beach County prosecutors released the evidence Thursday and say it's what helped detectives arrest Keen in September at the Virginia home she shared with her husband Michael Warren, who also happened to be Marlene Warren's widower.
Keen-Warren is facing charges for Marlene Warren's death.
Back in 1990, detectives say Keen-Warren knocked on Marlene Warren's door while holding flowers and balloons.
The clown fired once, hitting the woman in the face. She died two days later.
The Palm Beach County Sheriff’s Office says Keen-Warren was having an affair with the victim's husband, Michael Warren, who she would later go on to marry.
Michael Warren and Keen-Warren have denied that they were having an affair at the time, and the husband has not been charged in connection with the killing.
The clown left the scene and drove off in a white Chrysler LeBaron that was later connected to a car rental company that had ties to Michael Warren’s used auto dealership, investigators said.
Sheila Keen, then 27, worked for Michael Warren.
Prosecutors will seek the death penalty against the now-54-year-old.
Keen-Warren has pleaded not guilty and her attorney has said "she vehemently denies her guilt."
