Letters 'could affect' death penalty review

'April Fools' Day' killer writes to his father and lawyer, confessing to murder and seeking help

Two letters written by Lin Senhao, a former medical student who was convicted of killing his roommate Huang Yang with poison, might influence public opinion in his favor, said experts.

The letters were published in Shanghai's Dongfang Daily newspaper on Tuesday. In one letter to his father, on June 5, Lin wrote: "I did poison Huang. I have no other way but to confess the crime and I must."
