Los Angeles: The body of an experienced 50-year-old free diver clad in a wet suit was pulled from waters off Palos Verdes Peninsula on Saturday, near where she went missing a week earlier.

Authorities said Rebecca Weiss, of Marina del Rey, was found in a cove below the Terranea Resort. Coroner’s investigator Elissa Fleak said her agency had not yet established a cause of death and that an autopsy would be conducted on Sunday.

The body was discovered about 200 yards offshore in an area that was a favourite dive spot for Weiss and her husband. Alan Weiss went to a sheriff’s station on August 11 and told deputies that his wife of 20 years had not returned to their home after a planned dive in the cove.

He told investigators he had found her BMW in the resort parking lot and a bag containing her dive equipment by the shore.

Rebecca Weiss’ mother and brother were near the resort passing out fliers when recreational divers found the body about 11:30am. Vilma Causey wept and clutched a photo of her daughter as a search-and-rescue boat pulled the body from the water.

A diver involved in the recovery of the body later came ashore and had an emotional conversation with Causey before authorities escorted her away with her son, Bob, a Los Angeles County Sheriff’s Department sergeant, and daughter-in-law.

Causey told TV station KTLA last week that her son-in-law’s behaviour was “strange” and “not the reaction of a person that has somebody missing that is close to you.”

Alan Weiss, 60, has declined to comment. He was not on the beach on Saturday. Lieutenant Holly Francisco of the sheriff’s homicide bureau said she did not know whether Alan Weiss was aware that a body had been found, but described him as “very cooperative” with investigators.

“He met with detectives and provided a whole statement of his last encounter with her,” Francisco said.

She said the sheriff’s homicide unit was assigned to the case because it involved a missing adult, and Weiss offered detectives an account consistent with his initial report to deputies.

Asked whether investigators shared the suspicions aired by Rebecca Weiss’ family in the media, Francisco replied, “No.” She noted that the homicide unit’s purview includes drownings as well as murders.
