Father Robert 'Bob' Hoeffner was gunned down at his Florida home by Brandon Kapas, 24, who also fatally shot Hoeffner's sister, Sally, before turning the gun on his own grandfather.
The bloodbath on January 28 last year only came to an end when Kapas was killed by officers during a shootout at a family member's Palm Bay home.
The triple murder sent shockwaves through the community, but Hoeffner's memory has since been tainted by a series of allegations he carried out a decades-long campaign of sexual abuse.
More than 40 pages of graphic notes describing sick acts against children were found by police at Hoeffner's home following his murder, though officials said they cannot be sure who they were written by.
Kapas' aunt told investigators her nephew was among Hoeffner's alleged victims while he was a young boy attending St. Joseph Catholic School, according to a police report.
Since Hoeffner's death, three individuals have come forward with similar allegations of abuse in lawsuits filed against the Diocese of Orlando, accusing the religious authority of engaging in a cover up.
The latest pair of lawsuits, both filed in state court on last month, were filed by two men who claim Hoeffner repeatedly molested them in the late 1980s when they were 14 to 15-years-old.
The explosive filings accuse Hoeffner's sister of facilitating and being present for some of the alleged abuse.
The only alleged victim to come forward publicly is Shawn Teuber, 26, who also sued the Diocese of Orlando in May.
Teuber was friends with Kapas and said in his lawsuit that Hoeffner abused him through seventh and eighth grade while at St. Joseph Catholic School from 2012 through 2014.
The suit claimed that Hoeffner molested Teuber in the school counselor's office, at Hoeffner's home and in a car when he was teaching the boy how to drive.
'I've carried this pain for years, and I couldn't stay silent any longer,' Teuber said. 'By sharing my story, I hope to show others they're not alone and to make sure this doesn't happen to another person.'
The Diocese of Orlando and St. Joseph Catholic Church filed a motion to dismiss Teuber's lawsuit late last month.
In a statement to Daily Mail, a spokeswoman for the Diocese said the organization is 'aware of the new claims against Fr. Robert Hoeffner and have been evaluating the allegations'.
'We reiterate that the Diocese of Orlando was not made aware of any allegations of abuse during Fr. Hoeffner’s pastoral leadership or after he retired in 2016,' the spokeswoman continued.
After Kapas' rampage Teuber offered a sworn statement to police that he had been groomed and violated by the priest.
Kapas's aunt, Kourtney Bonilla, told police said that Kapas had a weird' and 'long-standing relationship' with Hoeffner going back to his teen years at the Catholic school.
Bonilla said Hoeffner shared a bank account with Kapas and that he bought a vehicle for him when he got his driver's license.
She said that even though Kapas never confided in her, she 'firmly believed' Hoeffner sexually abused him as a child.
Lisa Hoeffner, the priest's other sister, also spoke with police and corroborated certain details that Bonilla offered, including the shared bank account.
Detectives also looked through Hoeffner's phone and found bizarre text messages from Kapas on January 27, the day before he and sister Sally were found dead in their home.
Text messages sent by Kapas read in-part, 'You have woken up all of Egypt... Ancient ones know what you have done...'
Multiple plaintiffs accused Sally Hoeffner, the priest's sister of either being present for the alleged sexual abuse or doing nothing to stop it. Sally was shot and killed by Kapas alongside her brother
After Teuber sued in May, two more anonymous plaintiffs filed suits on July 1 containing similar accusations.
One of the plaintiffs, John Doe I, said Hoeffner walked around his Orlando home naked, while also demanding he do the same.
The same lawsuit claimed the alleged victim was inappropriately touched by Hoeffner during so-called therapy sessions that Sally Hoeffner was accused of participating in.
Hoeffner also put a down payment on John Doe I's first car, according to the lawsuit.
The other plaintiff, John Doe II, said in his lawsuit that he met Hoeffner in 1987 at age 14 when he became an altar boy at St. Isaac Jogues Catholic Church.
He was allegedly sexually abused and forced to commit acts on Hoeffner during private 'prayer sessions', according to the complaint.
The abuse only stopped when Hoeffner allegedly grabbed the boy by the face and kissed him on the lips in front of his mother, who then publicly admonished the priest and took her son out of altar service, per the suit.
Both lawsuits said Hoeffner of spending time alone with young boys in a canoe out on a lake near the San Pedro Retreat Center as early as the mid-1980s.
Both also claimed that it was well known in the community at the time that boys lived at his residence.
Herman Law, the firm representing the three alleged victims, is demanding $25 million in damages from the Diocese for 'giving [Hoeffner] unfettered and unsupervised access to a vulnerable population of underage males'.
The Diocese of Orlando was hit with yet another lawsuit on July 1 accusing a different priest of committing sexual abuse in two central Florida parishes.
George Zina, now a priest at St. Elias Catholic Church Maronite Center in Roanoke, Virginia, was named as the person who allegedly molested a young boy in the mid-2000s.
The Diocese of Orlando told Daily Mail that Zina 'was not a priest of the Diocese of Orlando and was not employed by the Diocese', adding that it was unaware of any claims against him at the time.
The Eparchy of Saint Maron of Brooklyn, which oversees all East Coast Maronite Catholic Churches, including St. Elias, said that since no criminal charges have been filed against Zina, it has decided to keep him as a priest.
'The Eparchy has never received a complaint of this nature against Father Zina in his more than 38 years of priestly ministry,' a statement read.
