Husband Charged With Murder After Arson Kills Wife, Spares Daughter

A Harrisburg couple faced a nightmare scenario last Saturday morning when a fire erupted inside their home on the 2900 block of Green Street. Emergency crews found Dr. Julia Pederson, 41, dead in her bed at about 7:05 am. She worked as a pediatrician for the University of Pittsburgh Medical Center. Her husband, Jonathan Gatto, 42, was charged with first-degree murder after police determined the blaze did not cause her death.

Prosecutors say Gatto strangled his wife and then started the fire while their seven-year-old daughter slept nearby in another room. The little girl survived the ordeal unharmed. Police arrested Gatto on Wednesday. Beyond the murder charge, he faces counts for abuse of a corpse, tampering with evidence, endangering children, arson, and aggravated arson.

Gatto told investigators that the marriage was falling apart and they were planning how to tell their daughter about the separation. He claimed smoke alarms woke him up around 2 am or later. In his account, he rushed downstairs to save their young child but burned his hand trying to enter the bedroom where Pederson lay. The autopsy confirmed she died from traumatic injuries before flames touched her body.

The scene showed only light smoke coming from the house. A Pennsylvania State Police fire marshal ruled the fire intentional after inspecting the site. First responders performed CPR on Pederson at the home and then rushed her to Penn State Health Holy Spirit Medical Center, where she was declared dead. Her death was officially classified as a homicide.

According to reports, Pederson had been struggling with migraines and started new medication around October 9. Gatto told police he heard a loud noise resembling someone falling down the stairs near midnight. He allegedly asked if she was okay, received a mumbled response, and then she closed her bedroom door. He reportedly tried again later to bring her ibuprofen but found her startled by his return.

Pederson's sister launched a GoFundMe campaign to cover funeral costs and set up a scholarship for the surviving daughter, who is in second grade. The tragedy highlights how quickly a domestic dispute can turn into something far darker. Families like Pederson's now face an unimaginable loss while communities grapple with the reality of such violent crimes.

About $23,800 had been raised by Thursday in support of Dr. Pederson's family. She was a Harvard University graduate who earned her medical degree from Stanford's School of Medicine before completing her pediatric residency at Lurie Children's Hospital in Chicago. The University of Pittsburgh Medical Center told CBS21 on Tuesday that it felt deeply saddened by the loss of this beloved pediatrician and valued member of its Children's Community Pediatrics team. A statement released by the hospital noted that Dr. Pederson devoted her career to caring for children and supporting families, adding that her loss is felt deeply by colleagues, patients, and the communities she served. She joined the hospital in February according to a Facebook post from UPMC. Fran Chardo, the Dauphin County district attorney, called the circumstances surrounding her death devastating. With the domestic violence case, it can happen, Chardo said according to WGAL. These things occur suddenly and without any warning. Gatto has been denied bail and remained at Dauphin County Prison as of Wednesday based on Pennsylvania court records viewed by the Daily Mail. He is scheduled to appear in court on October 28 for a preliminary hearing. Court records show he did not have an attorney listed, and legal filings said he had not requested a public defender. The Daily Mail has reached out to the Dauphin County District Attorney's Office and the Dauphin County Coroner's Office for further comment regarding these tragic events.
