A door at Cameron Heights Apartments, 1114 W. Wisconsin St., is covered in police tape Monday morning.

Authorities say a Portage man shot and killed his girlfriend, a Pardeeville woman, in his apartment early Sunday.

The Portage Police Department arrested Jason R. Hardt, 25, of Portage, on a tentative charge of first-degree reckless homicide.

The victim is Rebecca Weisenberger, 25, of Pardeeville. Authorities say Hardt shot her at his apartment at Cameron Heights Apartments, 1114 W. Wisconsin St.

Downstairs neighbor Joe Weidner, 33, said he heard a gunshot at about 12:30 a.m. Sunday and ran upstairs. He saw Hardt "covered in blood."

"He said ‘Help me - call 911,'" Weidner said.

Weidner said he, along with another neighbor, helped Hardt into an apartment directly across the hall from Hardt's, then checked a woman who was lying on the floor in the living room to see if he could help her.

"She didn't have any kind of a pulse," Weidner said.

He then called 911, he said.

A handgun was on the floor in the living room, he said.

The "About Me" section of Weisenberger's profile on Facebook, the online social networking Web site, states:

"I live in Pardeeville WI though I spend most of my time in Portage. I currently work at the local Subway restaurant but have dreams of graduating UWSP with a major in English and a double minor in writing and spanish. I would eventually like to get my masters and maybe work in publishing. I am taking an online course in college algebra right now to try and make that dream a reality. It's challenging but it will all be worth it in the end. I'm scared and exited at the same time!"

One of her favorite quotations, according to Facebook, was: "If people continue to live like there's no tomorrow, someday there really won't be one."

Her last posting on the Web site was at 9:17 p.m. Saturday, about three hours before she died. It said: "Rebecca is getting ready 2 party!"

Weidner, who has lived in Portage about five years, said his children, ages six months, 3 and 4 years old, slept through the incident.

Weidner said the incident shocked him, taking place in a "wonderful" city such as Portage.

"This is the kind of stuff you hear about in Chicago," he said.

According to her obituary, Weisenberger was born June 1, 1983, in Jefferson City, Mo., to Thomas and Sharon Weisenberger. She graduated from Portage High School in 2001 and had attended the University of Wisconsin-Oshkosh.
