The mystery girl in the lab

Abandoned Warehouse of Death

Booth and Brennan arrived at Dr Vasco's residence in downtown DC 
"Booth are you sure this is the right address or are we lost again" Brennan asked while turning to face Booth
" I'm sure" In front of their FBI SUV was a large warehouse of about two stories high it looked like it had had not been used in years
"You know what let's just get get out of the car and check it out" Booth said while getting out of the car Brennan followed suit .
Booth rolled the large door open revealing light inside the dark warehouse numerous rats scattered to safety as he opened the rusty spider web coated door
"Seems like a dump now why would a doctor's home address be an abandoned warehouse"
Brennan questioned.
"Bones stay behind me "
"I can take care of myself Booth you are not my babysitter"
As the two entered Booth turned on his flashlight and shined it across the dark hallway and his other hand held a gun in case the room had unexpected inhabitants his muscular build formed a stray shadow covering nearly half of the hall blocking light penetration leaving the room partially dark.
"Bones take a look at this " he yelled from across the room where Brennan was .
Brennan shined her flashlight to what Booth showed her .
"Booth there are several Human skulls in here "
She leaned into get a closer look
"Based on the degree of deterioration this victim had been dead for 2 to 3 years the brown ridge suggests African American the fusing of the skull and orbital sockets suggests she was between late twenties to early thirties she shape of the pubis suggests she has given birth"
Brennan said making her conclusions from the skull .
Booth was getting irritated by the smell as usual
"Looks that we may be dealing with a serial killer on our hands"
Brennan looked at Booth horror written all over her face

Booth made a call to the FBI crime scene technicians and sent out the address .
Brennan took out her blue light which she carried whenever they went to question a suspect. Most of her intrusions into household properties were not taken kindly but she did not care her work was to ensure that justice had been served .
She shone her blue light but found no blood evidence she took out a bottle from her purse which contained a mixture of hydrogen peroxide and luminol and sprayed the caseinogenic solution all over the wall and it produced glowing results.
The blood illuminated blue she searched for a pattern but was not fruitful it's like the killer knew that it would give him away .
She turned to the remains and examined them further.
