Knife-wielding man sneaks into USC student's apartment, writes on walls possibly with blood

EXPOSITION PARK, LOS ANGELES (KABC) -- It was trespasser terror for a University of Southern California student as a knife-wielding man snuck into her secured building and apartment as she slept.

Although the victim's apartment complex is near the USC campus, it is privately owned and managed.

Residents there are not mad at the university but frustrated with the management after a scary situation.

The study room on the fifth floor was in shambles after a man somehow got past security and into the West 27th Place apartments near Exposition Park early Tuesday morning.

The man wrote on the wall, likely using his own blood, and carved into the floor, possibly using a knife.

"Looking at it was straight out of a horror movie, and I felt so, so unsafe," said building resident Rachel Meyers.

Meyers Snapchatted video after the incident, and you could still see a hole left in the wall.

She said the man somehow made his way down the halls and into an apartment where a girl was sleeping.

"He broke into an apartment residence on the third floor, took a kitchen knife and was screaming that people were trying to kill him," Meyers added.

That girl called 911, and the suspect was eventually arrested by Los Angeles police officers.

Residents believe the suspect may have entered through the woman's balcony.

The building's management posted security notices on doors but not until at least a day after the incident.

Residents said building management is to blame and many added they don't feel safe.

Security working at the building on Wednesday said management had gone home for the night and no one was around to talk on camera.
