Sure enough, in the lower right corner, there was an arc from welding.
However, the green paint in that area had been worn off.
He stood up, pointed with his hand, "If I'm not mistaken, this area is likely the result of the gas canister being dragged upward, causing the protrusion to rub against the wall."
"Moreover, right above this protrusion, you can see multiple scratches on parts of the gas canister as well."
"These scratches must have also been caused by the gas canister coming into contact with the uneven surface outside the wall."
Although no fingerprints or biological information of the suspect have been found on the paint can, the marks on the gas canister match those at the scene perfectly.
Next, Jiang An set the gas canister down.
"At present, I can only say that his suspicion is very high."
"However, to determine if he is the murderer, we need more evidence."
Following that, Jiang An moved from the balcony to the entrance area of the living room.
