2429: Cannot Detect any Fingerprint

Cannot Detect any Fingerprint

Yun Shishi overthrew his reasoning, though. "Surely, the police can find a clue as long as they investigate, can they not? There shouldn't be anyone else on the second floor besides your daughter and the culprit."1

Lu Jingtian's father glanced at the actress and stopped short of replying to her. Meanwhile, Mu Yazhe chimed in, "The second floor wasn't deserted. It just happened to have a smaller crowd at that time."

Lu Bosheng nodded in agreement. "That's true. Before my daughter's arrival around midnight at the bar, most of the guests were on the second floor during the live singing. Only a few, who had successfully reserved downstairs seats, were at the dance floor. The rest were upstairs, listening to the performer onstage while drinking. One service staff did go up the second floor when Jingtian was with the culprit. She even remembered pouring a cup of tea for that person dressed in black. She also witnessed that person picking up the cup for a drink."

The woman frowned when she heard that. Walking to one side, she contemplated for a while before turning to declare with conviction, "In that case, it stands to reason that the cup should have the person's fingerprints on it! Glass is a pretty good 'fingerprint collector'; there should be more than one left behind, in fact."

The other man was looking rather hopeless by then. He shut his eyes and mumbled, "That's why I find it mind-boggling when I was told that they couldn't find any."

"Could the prints be wiped off?" The actress wondered aloud. "I read somewhere that fingerprints can be erased with hydrochloric acid, although I don't know how true that is."

The older woman was rather taken aback with this deduction, only to hear her husband responding, "The police told us that, with modern technology, even if the print is to be wiped off with hydrochloric acid, it can still constitute as a clue with partial print. Unlike in the past, there are rarely any unsolved cases nowadays. Basically, any case can be solved within a few days. Even if the culprit can get away with the lie detector, there is no getting away with the evidence left behind on the crime scene. Plus, if the culprit used hydrochloric acid, it would prove that the cup had been cleaned earlier. The thing is, the police technicians were able to pull off many fingerprints from the cup except for the culprit."

Yun Shishi was thoroughly stunned by what she had heard. "Only the culprit's fingerprint could not be retrieved?!"

"That's right."

"How's that possible?! Didn't you just say that one service staff saw the culprit drinking from the cup?! If that's true, then even if the police couldn't retrieve the fingerprint, they should at least be able to retrieve the person's residual saliva, shouldn't they?" exclaimed the young lady.

"It's basically impossible. Even the provincial forensic identification agencies don't have the capacity to perform saliva testing. DNA identification requires a certain amount of content, and if it's less than that, it can't be done."

The actress was, again, shocked by the information shared. "This is unbelievable…"

Her husband suddenly had an idea. "There's only one possibility for failing to extract a fingerprint."

"What can that be?" She turned around and asked with her eyes wide open.

"By destroying the fingerprints."

"Destroying the fingerprints?" The actress could not help laughing. "Our fingerprints can't be removed totally, even if the cut is made with a knife."

Mu Yazhe cut her off with a casual comment. "It'll be a different story if one is to slice the skin off the fingertips."

Yun Shishi: "…Slice off the skin?! You mean to slice it with a knife?"

That was literally cutting off flesh from the fingertips! How painful would that be?!
