RM1011, N Apartment

The noisy ringtones rings at the 8AM this morning. I hang up the call, contiuning to sleep. But after a while, the phone ring again.

"Who is speaking?" I ask impatiently.

"Sir, a murder case is just found at M Apartment. The victim is a woman." My colleague Andy said seriously.
As soon as I hear the word "murder", I immediately sit up from my bed.

"Tell me the case briefly." I say.

"Someone found the a corpse at Room 1503, and reported this case at arond 8AM this morning. Our preliminary judgment about the cause of death is excessive bleeding on the head." Andy says.

"Did you check the monitor of 15th flooe?" I say.

"I haven't yet." Andy says.

"Got it. I will go there as soon as possible. Could you send me an accurate address of M Apartment?"

"Sure. See you later" Andy says.

A few seconds after hanging up the phone, Andy send me the address.

I enter the address into the navigation app, and then drive to M Apartment.
