Chapter 3753: It was my mother who asked me to poison it.

The police officer explained his doubts.""You probably didn't expect this, but because old master Lu was suddenly sent to the hospital, the Lu family was in a panic, so this cup wasn't cleaned in time. Not only do you have your fingerprints on it, but there are also drug residues. Do you want me to bring you another copy of the chemical residue and drug residue test results from old master Lu's body?"

Yu yuanfan's face was pale and his body was trembling non-stop.

The cold sweat on his forehead started to roll down, and he felt like he was going to faint at any moment.

He was worried that the drug had settled at the bottom of the cup and didn't melt. Before the two old men came in, he picked up the cup and shook it a few times, and the fingerprints were on it.

The police officer sighed."I told you before that if you came clean before the fingerprint match was done, you could get a lighter punishment. But you didn't listen."
