Three people have been killed and 30 others wounded in at least six separate shooting near major university campuses across the US following a bloody weekend of Halloween, homecoming and football rivalry violence.

At least 6 people were wounded near the University of Delaware when a gunman opened fire in a packed downtown Newark, Delaware, street about 11 p.m. — sending costumed students fleeing for their lives.

Near Michigan State University in East Lansing, a psycho in a Michael Myers mask opened fire, wounding one person, Metro Detroit News reported. Another person was wounded in a separate shooting around 12:30 a.m. Sunday. It was not clear if the shootings were related.

At the University of Colorado in Boulder, one 19-year-old student was killed and another student wounded by a gunman at a massive house party attended by hundreds of students around 11:30 p.m., according to cops.

Two suspects have been ID’d, and police said they believe the men tried to force their way into the party about 90 minutes after cops shut it down and told revelers to go home.

In Birmingham, Alabama, one person was killed and eight wounded — one critically — in multiple shootings in the aftermath of the 85th Magic City Classic football game Saturday night. The matchup is a rivalry game between Alabama A&M and Alabama State, both historically black universities.

Police Chief Michael Pickett described the night as “two senseless acts of violence,” as witnesses described chaotic scenes during a tailgate outside of Birmingham’s Legion Field shortly before 8 p.m. Saturday, AL.com reported.

One person has been detained in connection with the shooting.

Near Illinois Wesleyan University in Bloomington-Normal, Illinois, a 19-year-old woman was killed, and seven others were wounded.

One of the victims was taken to the hospital in critical condition. Two Illinois Wesleyan students and an Illinois State University student were among the injured, WGLT reported.

In Bloomington, Indiana, at least seven people—four men and three women—were injured in a shooting on Kirkwood Avenue near the Indiana University campus at around 1:30 a.m. Sunday.

Officers heard “multiple gunshots” following an argument in a large crowd of Halloween revelers in the popular bar strip, Deputy Chief of Police Ryan Pedigo told WTHR.

The victims range in age from 17 to 27, and none are students or from Bloomington.

One 18-year-old was taken into custody, but police have not said whether he is the gunman. An AR-15-style handgun was also found at the scene.

Another weapon, an AK-47-style pistol, was found on one of the victims, cops said.

Multiple calibers of shell casings were found at the scene.

IU was celebrating homecoming and an overtime win over the Minnesota Golden Gophers earlier on Saturday — in addition to the Halloween festivities.
