A young Pennsylvania couple who were high school sweethearts are dead in a murder-suicide carried out by the husband less than two years after they tied the knot, police said.

Ryan Hosso, 26, gunned down his physician assistant wife, 25-year-old Madeline Spatafore, inside their Butler, Pa., home early Tuesday before retreating into nearby woods, where he turned the gun on himself, according to Pennsylvania State Police.

Hosso called his parents at some point between Spatafore’s murder and his suicide. During the brief call, he confessed to killing Spatafore and threatened to take his own life, cops said.

Hosso’s parents reported their son’s erratic behavior to authorities around 1:15 a.m. Tuesday.

When officers responded, they found Spatafore dead inside the home. Police used thermal drones to locate Hosso’s body in the woods, the Cranberry Eagle reported.

Spatafore sustained “multiple gunshot wounds,” while Hosso only had one injury, police said.

The couple tied the knot in Ohio in September 2024, according to their wedding registry.

They both graduated from Seneca Valley High School in Harmony, Pennsylvania — just 10 miles outside their home in Seven Fields, a borough of Butler.

Spatafore graduated from high school in 2019 and then attended Duquesne University. She graduated summa cum laude with a degree in health services in 2023.

She was employed as a critical care physician assistant at UPMC Presbyterian at the time of her death, according to her LinkedIn.

It’s unclear if or where Hosso went to college. He previously worked as a mechanical engineer at Vavco, a Pittsburgh-based engineering firm for the oil and gas industry, according to his LinkedIn.

The owner of Vavco told WPXI that Hasso hadn’t worked for the company in three or four years.

Police have not released a motive in the harrowing shootings. An investigation is ongoing.
