Moments after he witnessed his mother get hit and killed on a busy Watertown street Wednesday morning, Philip Horner climbed up to the door of the flatbed tow truck that struck her and began punching the driver, screaming as he swung his fists, according to a police report of the incident released Thursday.

When he hopped down into the street, Horner, 38, fell to the ground, eyewitnesses told authorities.

“I didn’t see anything,” the driver, 60-year-old Norton resident Thomas Fogerty, can be heard telling him in a video of the incident — seconds before Horner, springing back to his feet, pulled a knife from the fanny pack he wore and stabbed Fogerty multiple times, the report says.


Horner, who now faces charges of armed assault with intent to murder, assault and battery with a dangerous weapon, and resisting arrest, was arraigned in Waltham District Court Thursday where a judge ordered him held without bail.

Horner, a Quincy resident, was ordered to Bridgewater State Hospital for a 20-day psychiatric evaluation, according to the court clerk’s office. A not guilty plea was entered on his behalf.

Authorities said Thursday that Benita Horner, 68, of Belmont, was killed Wednesday morning when she was hit by an eastbound 10-wheel flatbed tow truck on Watertown Street (Route 16) near its intersection with Galen Street and Nonantum Road.

Police received a call around 11:20 a.m. for a “road rage incident,” Watertown Police Officer Orlando Rodriguez wrote in a report on file in the court clerk’s office.

On arrival, officers found Benita Horner pinned beneath the truck, he wrote. She was pronounced dead at the scene.

Eyewitnesses told Rodriguez that they saw Philip Horner “open the driver’s side door of the tow truck, enter the cabin and proceed to punch the operator of the tow truck” after the crash, Rodriguez wrote.

A cell phone video of the altercation obtained by authorities shows Philip Horner later take a knife from his fanny pack and stab Fogerty, according to a report written by Watertown Police Det. David MacNeil.


“I was able to observe the multiple stab wounds including, but not limited to, one directly in Mr. Fogerty’s back that Mr. Horner plunged into him and then twisted with force,” wrote MacNeil, who watched the video. “Mr. Fogerty fell to the ground saying, ‘I didn’t see anything,’ ‘Come on man.’”

When officers arrived at the scene, they found Philip Horner sitting in the street with a knife in his hand, Rodriguez wrote, adding that he actively resisted arrest.

He screamed, “He ran over my mother, he ran over my mother,” as police approached him, the report says.

Both Philip Horner and Fogerty were brought to hospitals Wednesday, and Fogerty remained hospitalized Thursday in critical condition, according to the Middlesex County District Attorney’s office.

Philip Horner is having difficulty remembering things, paying attention, and speaking, a court psychiatrist who examined him said at Thursday’s hearing, The Boston Globe reports. He tried to harm himself while in the hospital Wednesday night and has expressed thoughts of suicide, the doctor said.

District Court Judge Gregory Flynn approved prosecutors’ request for a dangerousness hearing, with Philip Horner scheduled to appear in court again on Oct. 10, the district attorney’s office said in a statement.

Authorities are asking anyone with information regarding Wednesday’s incident to contact the Massachusetts State Police assigned to the district attorney’s office at 781-897-6600 or Watertown police at 617-972-6500. The investigation into both the crash and stabbing remains ongoing.
