Anthony Todt, who police say confessed last week to killing his family, stabbed his wife and two sons, according to preliminary autopsy results.

Those results were released Thursday, along with a previously sealed arrest warrant affidavit for the Colchester business owner, offering new information on the family homicides that have shaken the Colchester community.

Megan Todt, 42, and the couple's three children were found dead in a second-floor bedroom in the home the family rented in Celebration, Fla. Megan had been stabbed twice. Their sons, 13-year-old Alek and 11-year-old Tyler, each had been stabbed once. Four-year-old Zoe had no evidence of injury, according to the warrant and report.

The autopsy report was not considered complete, as the results of toxicology tests had not yet been received. The medical examiner's office said it could be 10 to 12 weeks before those results are back.

All four deaths had been ruled homicides. The manner of death is still classified as pending.

The medical examiner's office also has not yet determined when Megan and her children were killed, but described the bodies as being in the early stages of decomposition.

The sworn arrest warrant affidavit by Osceola County Sheriff's Office Detective Cole Miller, which had been ordered sealed on Jan. 15, said that federal agents from the Department of Health who were surveilling the family's rental home at 202 Reserve Road saw Todt, who goes by Tony, walk into the home about 9 a.m. on Jan. 13.

Deputies from the sheriff's department arrived at the home and announced themselves at the front door. When no one answered, they went inside.

Deputies found Todt, who "appeared to be shaking" and "could barely stand." He told deputies that his wife was upstairs and was likely asleep, according to the warrant affidavit.

After calling out to Megan and hearing no response, deputies went upstairs, where they found Megan and her children "obviously deceased." The family dog also was found dead in the bedroom.

Todt was taken to a hospital for an evaluation and was held there after making threats, the affidavit said. He told paramedics he had taken Benadryl to try to commit suicide.

Miller and Detective R. Quinn went to the hospital to speak with Todt, who was "awake and alert" when they arrived. He agreed to speak with them after being read his rights and told them what happened, according to the affidavit. Todt's account of what happened to his family was still redacted from the affidavit.

Megan was found to have two stab wounds on the upper abdomen, and another on the right upper abdomen, according to the preliminary autopsy report. Alek was found to have a stab wound on the left upper abdomen. The medical examiner identified a stab wound on the upper abdomen of his younger brother, Tyler.

About 7 p.m. the day they were found, the bodies were removed from the home by the medical examiner's office. The condition of the bodies was consistent with the information Todt provided, the affidavit said.

Based on the investigation, Miller stated in the affidavit that the sheriff's office has probable cause to believe that Todt "acted with premeditated design, and murdered his wife and three children and the family dog."

Sheriff Russ Gibson said last week that it was believed the family was killed in late December.

Todt was charged on Jan. 15 with four counts of premeditated homicide and one count of animal cruelty and was being held without bond. He made his first court appearance on Jan. 16 but did not enter a plea.

Authorities had not yet identified a motive, but authorities in an affidavit unsealed Jan. 15 allege that Todt committed health care fraud by submitting false claims to Connecticut Medicaid and private insurance companies for years. On the day the bodies were discovered, police were at the house to execute a warrant stemming from an FBI and Health and Human Services-Office of Inspector General investigation in Connecticut.

Todt, who owns Family Physical Therapy and Performance Edge Sports LLC in Colchester and previously lived on Waterhole Road with his family, had allegedly been billing insurance companies for physical therapy sessions that never happened.

Public records show that the Todts and their businesses owed almost $100,000 in unpaid loans, and recently had been evicted from a condominium they were renting in Celebration, a small community near Disney World. Court records show the couple were being sued by P and Y Dordoy LLC for failing to make a $4,921 rental payment due on Dec. 1, 2019.

They were also being evicted from the home they were renting, where they were found dead.

The affidavit indicates Todt and his business took out loans or cash advances from more than 20 commercial lenders. He had stopped paying staff members of the business, who then stopped showing up for work, it said. His Colchester businesses were closed and locked up at the time he was arrested.

Family members of the Todts began to fear that the family was missing in early January, starting a Facebook group called "Looking for the Todt Family," which later was deleted.

In a news conference last week, Gibson said a family member contacted police in December for a welfare check thinking family members may have had the flu. Police said they went to the home on Dec. 29. No one answered the door and the blinds were closed, but deputies checked around the home and with neighbors.

"Nothing suspicious was noted," Gibson said.

On Jan. 9, the sheriff's office was contacted by federal agents about the investigation into Todt and visited the home again but could not make contact with any of the family members. Law enforcement next visited the home on Jan. 13, to serve the warrant. It was not yet clear if Todt had been staying inside the home with the decomposing bodies.

In Colchester, residents have been taking to social media to share theories on the case and Todt's motive. He was known in the community as a well-liked physical therapist, family man and active soccer coach who was great with kids.

Megan was a stay-at-home mom who homeschooled her children and cooked meals for the family from scratch. Alek and Tyler were accomplished musicians who both played the piano. Alek played violin, Tyler played guitar and Zoe was excited to start dance classes soon, the family's private music teacher, Bobbie Sedwick, said.

A candlelight vigil for the slain family is scheduled for 6 p.m. Friday on the town green in Colchester.
