Carl brought them the fingerprint analysis report.
"Our forensic examiner carefully lifted the fingerprints from the handgun! But I'm very sorry! There was only one person's set of fingerprints on the entire gun, and they matched the deceased's exactly!"
"You mean... there was only one person's set of fingerprints on the gun? Only Cheng Hui's?"
"Yes! That is exactly what the test results showed!"
Song Ning was astonished. "But that makes no sense! Even if Cheng Hui was the murderer, how did she get that handgun into Mike's house? What about whoever supplied her with the weapon? Didn't they leave any fingerprints?"

"The deceased fell on the lawn, and Mike's lawn is very well maintained! So there shouldn't have been soil on so many parts of the gun! Our officers have already returned to the scene. I believe they'll bring back new information soon!"

Someone had hidden the handgun in the flower bed beforehand. Cheng Hui had left the living room and entered the garden, retrieved the gun from the flower bed, aimed at Kurt on the second floor, and fired. She was then shot dead by security guards who rushed over
