The man responsible for murdering four people at a Kentucky pool party has been identified as a 21 year-old sex criminal who murdered his ex-girlfriend before turning the gun on himself.

Police in Kentucky were called to the 2600 block of Ridgecrest Drive in Florence just before 3am in the early hours of Saturday morning. 

On arrival, police found four people dead and three other critically injured victims who were taken to the ICU at a nearby Hospital.

The suspect in the shooting Chase Garvey, 21, fled the scene in his own vehicle before he crashed, with officers finding him dead of a self-inflicted gunshot wound. 

The four people Garvey is accused of killing have since been identified as Melissa Parrett, 44, Delaney Eary, 19, Shane Miller, 20 and Hayden Rybicki, 20. 

Sources told Channel3 NOW that Eary had been the former girlfriend of Garvey. 

The home that the party was being held at had belonged to the Parrett family, who were celebrating a birthday with a pool party.

During a press conference Saturday afternoon, Florence Police Chief Jeff Mallery said Garvey had not been invited to the party but had showed up. 

Mallery added that he was known to the partygoers, and that their initial investigation had revealed that Garvey had been acting alone. 

Images on his social media show him clutching a sniper rifle, a hand gun and a shotgun.  

Garvey was known to police before the shooting on Saturday, having been arrested and charged in 2021 for the rape of a 13-year-old girl. 

In April of last year, he was sentenced to five years of probation after pleading guilty to unlawful transaction with a minor in the second degree. 

According to a report at the time by Fox19, the victim told police she had been messaging Garvey on Snapchat weeks before the incident. 

The report says that the girl had told Garvey she was 13, and that they met at an apartment complex inside his vehicle. 

The girl told police that she said to Garvey that 'she didn't want to do anything sexual' when Garvey held her hands down and raped her. 

Garvey, then 18, admitted in a police interview to having sex with the girl and said the girl had performed oral sex on him prior. 

Police in Florence have said that the investigation into the mass shooting on Saturday is still under investigation. 

Mallery continued: 'We’ve never dealt with this before. I know it’s going on throughout the nation, but this is the first time that we’ve had a mass shooting in Florence. 

'It is very emotional. And my emotions are for the victims, their families, the officers that responded and everybody that was touched by this situation.'
