Philip Keller, aged 39, compiled a 2-6 record as a brawler, and most recently competed for Titan FC on three occasions from August 2019 to September 2020.

On May 15, at around 11:13 AM, Keller allegedly called 911 to report that his fiancee - Alicia "Red" Campitelli - was dead while someone had possibly broken into their apartment in Merritt island.

"[He] reported that Campitelli was not conscious and not breathing, and then disconnected the 911 call," Brevard County Sheriff Wayne Ivey said.

Ivey's deputies arrived at the residence and honed in on Keller in their investigations when noticing he had injuries such as what looked like a gunshot wound, the Sheriff said.

When questioned, one neighbor had told investigators he heard gunshots around 1 AM at the apartment complex too.

In the days that followed the death, officials raked through surveillance video footage that showed Keller making transactions using his fiancee's account details after the gunshots had been heard. But only hours later, the following morning, did he call 911.

According to an affidavit, Keller is also accused of using Campitelli's bank card to make multiple withdrawals of hundreds of dollars. 

As revealed by Ivey, Keller shared details about the case with a friend, who then contacted its investigators to set up a recorded phone call whereby he confessed to the killing.

"I killed her, bro. I killed her high as [expletive]. I did it. I don’t know how I did it, but I can’t live with myself knowing that," Keller is recorded saying, detectives insist.

"I did it. I’m so (expletive) sorry, man," he reportedly told the friend, in addition to admitting to being on MDMA and disposing of the murder weapon - which he shot her in "cold blood" with twice - in a barge canal located off Courtenay Parkway in the northern reaches of Merritt Island.

After listening to the confession, while the local community mourned Campitelli's loss, deputies went after Keller - who reportedly jumped into a creek before being arrested.

Charged with first-degree premeditated murder, Keller is currently being held without bail after appearing before Judge Benjamin Garagozolo Friday afternoon at the Brevard County Jail Complex.

His next appearance in court will be in front of Judge Thomas Brown on Monday, June 17 for arraignment at Viera's Moore Justice Center, where he could be sentenced to life in prison or even the death penalty.
