Penn State Police Services arrested two students this week in connection with the throwing of large rocks off the top of an eight-story residence hall early last Friday.

No one was hit with rocks, but three women who reported it to residence hall staff said it seemed like a racially motivated attack.

On Tuesday, police charged Evan J. Gugliuzza, 18, and William P. Loftus, 19, with recklessly endangering another person, criminal trespass and disorderly conduct. Their preliminary hearing is scheduled for Wednesday.

The police report says three black female students were walking near Pollock Residence Halls just after midnight on Sept. 29.

The three heard several rocks hit the sidewalk close to where they were walking, and they began to run, the report says.

Looking up, they saw two white men standing on the roof of Shulze Hall. The women went inside Shulze Hall and contacted a resident assistant, according to the report.

Two Penn State Police officers arrived and went to the roof of the building. There, they found three men — two of them were white, and the third was black, police said.

The three men said they were friends and admitted to being on the roof for about 10 minutes, the report says. They told police they'd climbed up there to look at the stars and did not throw rocks. They also admitted they were not residents of the hall and were not supposed to be there, according to the report.

Gugliuzza and Loftus told police they'd been drinking alcohol earlier that evening, the report says.

Police say in the report that Gugliuzza and Loftus were in the same area of the roof where the three women reported seeing the two white men.

Gugliuzza and Loftus, the two white students, were on the upper part of the roof when police arrived, but the third man was on a lower part of the roof.

Police said they found large rocks on the sidewalk similar to ones on the roof. They recorded one 34 feet away from the building and another 104 feet away.

Two of the three women who reported the attack were out of town yesterday evening for fall break. The third said she would prefer not to be quoted in the newspaper until the other two returned.

She did confirm that they believed they were targeted with rocks because of their race.

In the police report, the three black women say that the rocks seemed to be aimed at them, but not at other non-black students on the sidewalk.

Gugliuzza declined to comment yesterday. Loftus could not be reached for comment.

All the people involved are listed as students in the Penn State directory.
