While his son slept 50-year-old Tan Lam repeatedly struck his wife in the head with a framing hammer. The body of Melody Lam was discovered after a call was made to police from a man claiming to have killed his wife.
The office arrived at the house and was told, by Lam, that he had killed his wife and that he did not want his children to wake up and see the body. The affidavit also says that Lam says that voices told him to murder his wife with the hammer.
Lam's attorney is exploring the possibility of an insanity defense but that it is still too early to decide.
The couple's two children (6 and 8) are being cared for by relatives.
