ALHAMBRA — An Monterey Park man will spend the rest of his life in prison following his sentencing Thursday for kidnapping a San Gabriel Valley woman, slitting her throat, leaving her for dead in the desert and then attempting to extort a ransom from her father, authorities said.

Alhambra Superior Court Judge Candace Beason sentenced Deqiang Song, 26, to life in prison without the possibility of parol for the crime of kidnapping for ransom, as well as life in prison plus four years for the attempted murder of his then-21-year-old victim, Los Angeles County District Attorney’s spokeswoman Shiara Davila Morales said.

Beason further ordered that the sentences be served consecutively.

“We’re very pleased that he’ll be behind bars for the rest of his life. It’s appropriate for this heinous crime,” district attorney’s spokeswoman Sandi Gibbons said.

Song met his victim through a mutual friend and took her to the Westfield Santa Anita shopping mall in Arcadia on Sept. 8, 2010.

But the outing took a horrific turn when Song took a detour, driving the woman out to a remote area of desert in San Bernardino County, investigators said.

Song tied the woman up and used her cell phone to call the victims’ father and demand a ransom, district attorney’s officials said.

While haggling over the price, Song strangled the young woman, slit her throat and left her to die in the desert, investigators said.

Despite her severe injuries, the woman managed to walk about half a mile to the nearest home to seek help, according to Detective Michael Soop of the Los Angeles County Sheriff’s Major Crimes Bureau.

Not knowing that his victim has been found alive, Song continued making arrangements with the woman’s father to pay a ransom, ultimately settling on the figure of $10,000.

Song was also unaware that the victim’s father was working with sheriff’s detectives, who arrested him when he arrived to collect the money at an undisclosed meeting place in San Gabriel.

Song moved to Chicago in 2008 from the Shen-Yang Province of China on a student visa, officials said. He moved to Monterey Park in July of 2010.
