Police arrest suspect in UMass Amherst armed assault

Police have arrested a suspect who triggered a campus lockdown at UMass Amherst on Thursday.

Two suspects allegedly assaulted a student on on the UMass-Amherst campus Thursday night and triggered a shelter-in-place order. 

On Friday. Framingham Police were contacted by UMass-Amherst police about the alleged assault. As a result of their information, Framingham Police officers, along with State Police, searched two locations in Framingham. 

The suspects were not located at those locations, but a car wanted in connection with the assault was found at one of the locations and was impounded. 

William McKeown, 19 of Framingham, surrendered himself to police around 12:45 p.m. on Friday. 

McKeown is charged with assault and battery with a dangerous weapon, assault and battery and armed robbery. 

Police said they are speaking with a second suspect.

Police said the second suspect is not a UMass student and is not from the Amherst area.  He is not facing any charges at the moment.

UMass, in a statement, said the alert was issued after two people were involved in an armed assault on a student in Pierpont Hall and fled campus.

The university says a handgun was displayed during the incident at around 5:17 p.m. in Pierpont Hall at the campus. 

Police believe the suspects targeted the victim and that they know the victim. 

According to police, surveillance video shows the suspects were escorted into the residence hall by a student. 

There were not reports of shots fired. 

The assault victim suffered a head laceration and is being treated at a hospital in Northhampton. 

The shelter-in-place order was lifted at around 7 p.m. 

On Thursday evening, the university issued its first alert about an armed person on campus. 

UMass-Amherst later issued suspect descriptions.
