The Artist II

Apartment Building, Sussex Rd

After Davies explained the situation in hand to Sam. They proceeded with their investigation in the apartment building. Davies interviewed each of the tenants with Marco, whilst Jones instructed the small team of forensic techs of their tasks. 

Levi on the other hand stayed inside Michael Scott's flat, looking over the victim's possessions to build a psychological profile on the man. 

Their priority was to figure out whether or not the building was a threat to its residents and their neighbors. And so, they placed the apartment building in lockdown, in search of the source. And since the paint was the common source of lead, the techs tested the walls with a portable x-ray analyzer first. 

Water, air, and the cooking utensils in Michael Scott's abode were also collected to be tested for any trace of lead.
