Police are searching for a man with a violent criminal history who is now accused in the stabbing death of a York City man Tuesday night.

In a news release late Thursday, April 25, York City Police said Jordan Mantilla, 22, is wanted on a homicide charge.

Jason Markley, 27, was fatally stabbed in the 500 block of Wallace Street about 10:30 p.m. Tuesday, April 23, according to police. 

The York County Coroner's Office said Markley was stabbed in the chest. 

Mantilla is described as 5-foot-7, 150 pounds, with brown eyes and brown hair.

Anyone with information on Mantilla's whereabouts can contact York City Police at 717-846-1234. Or anonymously text "Yorktips" and your information to 847411.

Investigation: According to charging documents, Takeisha Fountain, Mantilla's girlfriend, texted Markley to purchase marijuana from him that night. 

Markley was walking near her home in the 500 block of Wallace Street that night, and he told her he would be right back after passing her home, police said.

One witness told police he saw Mantilla "do something" to Markley, causing Markley to drop his beer bottle and fall to the ground, court documents allege.

That witness, who is not named in charging documents, told police there was no one around but the Mantilla and Markley, police said.

Lt. William Wentz, who supervises the detective bureau, said Friday, April 26, that detectives believe there Mantilla was the only one involved at the scene. 

On Friday he said investigators do not have a motive in the slaying

Investigators searched surveillance footage from the area and found Mantilla running from the area after the incident, police said.

Photos of him were disseminated Tuesday, which led to one person recognizing him, court documents allege.

That person said told authorities that Mantilla pulled a knife on him and said "I'm nice with a knife," outside an East Philadelphia Street convenience store, police said. 

Investigators identified Mantilla from previous investigations, according to court documents.

Police said Mantilla lives on the 500 block of Walnut Street with his girlfriend.

Mantilla: Mantilla's criminal history involves two incidents in York City in 2017. 

In August 2017, York City Police said Mantilla and his brother attacked a 50-year-old man with a machete, metal pipes and a baseball bat in an apartment in the 100 block of East South Street.

Police said the two seriously injured the man, who was a tenant in the apartment that belonged to their grandfather.

In October, he pleaded guilty to simple assault and received a time-served prison sentence — 350 days. His other charges, which included aggravated assault, were dismissed, according to online court records.

His brother, Eric Mantilla Jr., 23, pleaded guilty to aggravated assault in November. He was given a time-served prison sentence of 278 days, according to online court records.

In May 2017, York City Police said Jordan Mantilla pointed a gun at a woman and her two children in the 200 block of Kurtz Avenue while he was "extremely angry." 

Jordan Mantilla also threatened the woman, a former roommate of his, with a knife, police said at the time.

During Jordan Mantilla's preliminary hearing in that case in June 2017, the majority of the charges in that case, including robbery, were withdrawn.

He eventually pleaded guilty in July to carrying a firearm without a license, and he was sentenced to three to 23 months in York County Prison.
