Police yesterday released additional details about the case of a Phnom Penh man and his mistress accused of slashing the throat of the man’s pregnant wife, saying the killing was a premeditated act carried out in tandem by the two suspects.

Deputy Phnom Penh municipal police chief Chuon Narin said yesterday that husband Si Lou Henglong, 32, had allegedly prepped the murder of his wife, Chou Ly Chou, by leaving gloves, a murder weapon and a key to the home’s safe for his mistress, Sovann Voleak, 22, to use while he left the house.

“Based on the suspects’ answers and the evidence gathered by police, we have decided to charge them with premeditated murder,” Narin said.

The pair is expected to be sent to court today, he added.

Narin said Henglong had unlocked the doors of his Meanchey district home, including the one to his wife’s bedroom. He then allegedly placed the keys to his safe on a table before stashing a motorcycle basket containing a pair of gloves and a knife under his house for Voleak to find.

After Henglong left the house while his wife slept, Narin continued, Voleak arrived and allegedly used the gloves and knife to slash and stab Ly Chou in the throat, then made off with several pieces of jewellery and about $6,800 in cash.
