NEW YORK (AP) _ A teen-age girl and her boyfriend have admitted killing the girl's parents and dumping their bodies into the East River, a prosecutor said.

Eric Louissaint, 20, and Connie Leung, 17, gave ``videotaped full confessions'' to the murders of Stephen Leung, 55, and his wife Chilin, 41, Assistant District Attorney Todd Harrison said during their arraignment on murder charges Friday.

Police said the couple were angry that Leung's parents, immigrants from Hong Kong, disapproved of their relationship.

Louissaint was arraigned on two counts of first-degree murder, punishable by death or life in prison without parole.

Leung was charged with two counts of second-degree murder, punishable by 25 years to life. She does not face a capital murder charge because of her age.

Harrison said Louissaint and Leung went to the parents' apartment on Nov. 2, strangled her father while he watched television, then waited for her mother to come home and strangled her.

Harrison said the two bodies were left in the apartment for several days, then thrown into the river.

The body of Stephen Leung, a waiter at a posh Manhattan restaurant, was recovered on Nov. 10. Police are still looking for the body of his wife, who also worked at a Chinese restaurant.

The killings were discovered when Connie Leung's sister called police to report that her parents were missing.

Police on Wednesday arrested the couple at a YMCA where they were staying. A bail hearing is set for Dec. 5.
