It took a Delaware County jury about 30 minutes Thursday to convict a Clifton Heights man of first-degree murder in a random, unprovoked stabbing that killed a 15-year-old boy as he was walking home.

Marson Weh, 39, was also convicted of possession of an instrument of crime in the April 2023 death of Michael Garr, a sophomore at Upper Darby High School.
Weh will be sentenced in November to life in prison for stabbing Gar 11 times, including once in the throat, according to District Attorney Tanner Rouse.
The two were strangers, Rouse said, and had “no earthly connection.” The DA said Weh offered no motive for the stabbing.
A passerby, Ian Coughlan, tried to help Garr, but his injuries were too severe, and he died of cardiac arrest before medics could arrive.
The prosecutor said the case would make the “worst episode of Dateline,” one without any twists and leaves no room for alternate theories or interpretation.
No one else was near Garr that night, he said, as Weh was seen “hunting, stalking” the teenager for more than a mile.
When Weh was arrested, he was still wearing parts of his “kill suit,” nondescript clothing that included thermal underwear stained with Garr’s blood, Rouse said. And he was still carrying the murder weapon, a folding knife that matched the dimensions of Garr’s fatal wounds and still had his dried blood caked in its handle.
“See this for what it is,” Rouse said. “Because when you only consider the blood on his pants, the blood on his knife, that alone proves he is guilty. There is no other explanation, no reasonable doubt.”
After the killing, investigators quickly identified Weh through surveillance footage, which recorded him following Garr for more than a mile. Gradually, prosecutors said, he closed the distance between them, and attacked Garr as they approached Brunswick Avenue near Bridge Street in Drexel Hill.
Weh’s attorney, Ian McCurdy, conceded in his closing arguments that it would “strain credulity” to say there wasn’t evidence to prove that Weh killed Garr.
Still, he urged jurors to consider that prosecutors had failed to explain his intent in doing so.
“As horrible as this situation is, the death of a young man killed way too early his life, this boils down to did the Commonwealth prove the case beyond a reasonable doubt,” he said
McCurdy supported his contention by citing a two-minute window of time where neither Garr nor Weh were recorded on surveillance video.
“The point is we just don’t know what happened in that small bit of time,” he said. “And that’s why I suggest to you the Commonwealth hasn’t proven that Marson Weh killed Michael Garr with malice.”
In responding to McCurdy’s theory of the case, Rouse, the district attorney, did not mince words: The evidence that Weh intentionally killed Garr, a crime that constitutes first-degree murder, he said, is overwhelming.
Beyond that, he said, Weh confessed to killing Garr during an interview with detectives. And he showed what Rouse described as a consciousness of guilt by soaking the hoodie and he gloves he wore on the night of the attack in ammonia — detectives found the items in that condition when they searched his home days later.
Rouse urged the jurors to convict Weh of first-degree murder, likening doing so to parents protecting their children from the evils of the world.
“There is simply no getting around the evidence,” he said. “You cannot stab someone in the throat and not mean it.
“That kid had no chance.”
