Authorities say 1 person has been charged in connection with the gunfire; police have a strong belief there were multiple shooters

LOWER OXFORD TWP, Pa. (WPVI) -- There are still many questions surrounding the deadly mass shooting on the campus of Lincoln University this weekend.
One person was killed and six were wounded in the shooting Saturday night, and one person is in custody.
Authorities don't believe it was a planned mass attack -- instead, they said, it appears the gunfire broke out suddenly in the middle of the homecoming activities.
It happened around 9:30 p.m. on Saturday outside the International Cultural Center during homecoming celebrations following the school's football game.
Speaking at a news conference Sunday evening, authorities said they believe more than one person fired shots during the incident.

Investigators are reviewing videos from people who were at the scene and are asking anyone with footage to share it with the FBI.
Authorities identified the person who was killed as Jujuan Jeffers, 20, of Wilmington, Delaware, and said he died just after midnight after suffering a gunshot wound to the head.
The six people who were wounded are expected to recover, officials said. They range in age from 20 to 25. One is a current Lincoln University student and another is a graduate. The others have no direct connection to the school, according to officials.
Zecqueous Morgan Thompson has been arrested and charged with carrying a concealed gun without a license. Investigators haven't confirmed whether his weapon was used in the shooting. He is being held at Chester County Prison on $25,000 cash bail.
Lincoln University students, alumni, and community members gathered Monday for a moment of healing and reflection.
Kofi Dadson, a Lincoln alum, said he was enjoying the festivities when the chaos began.
"I automatically felt in danger cause it was like this does not happen at homecoming. Homecoming is a place we come to connect with our loved ones," Dadson said.
He recalled the panic that unfolded.
"People were running towards us saying, 'There was a gunshot, there was a gunshot.' Then somebody called my line brother and was like, 'Yo somebody got shot in the head.'"
Amy Marks Delaney, who lives across the street in Chester County, said she was home when she heard the gunfire.
"It's a wonderful community. A wonderful place to live, so I was just terrified for everybody," she said. "I hope that people can be there for each other and not let this define them."

Lincoln University, a historically Black university, is located in the southeastern part of Pennsylvania.
In a statement on social media, the university said classes would be canceled on Monday.
"What occurred last night was tragic for our students, our families, and our community." the statement said. "Gun violence happens far too often in our country, and we are heartbroken that Lincoln University and its students are among the latest victims of such senseless violence."
Pennsylvania Gov. Josh Shapiro said in a post to X on Sunday afternoon that his administration has been in contact with university officials since the shooting occurred. The governor said he has offered the "full support" of the state to Lincoln University President Brenda Allen, adding that the Pennsylvania State Police stands ready to help Barrena-Sarobe's office with the investigation.
In the statement, Shapiro said the weekend "should have been spent celebrating the legacy of our nation's first degree-granting HBCU, not putting the pieces together after a mass shooting."
Shapiro added that he and his wife, Lori, "are praying for the six people injured, the families sick with worry, and the one soul who will not come home. May their memory be a blessing."
Lincoln University has suspended classes for Monday. Counseling services will be available throughout the week.
The university will also hold a healing and reflection event at noon on Monday.
Authorities are asking anyone with information to contact 1-800-CALLFBI. You can also submit photos and video to the FBI website.
