California newlyweds Durga Moparti and Rajesh Gutta are supposed to be on their honeymoon - but instead they have spent the past three days desperately searching for the bride's father, who vanished from the wedding reception Saturday.

Prasad Moparti, 55, was last seen by family members walking down a road outside the Grand Island Mansion in Walnut Grove, which served as the setting of his daughter's traditional Indian wedding ceremony.

According to relatives, he arrived in California from India about a month ago to walk his daughter down the aisle and was feeling homesick.

‘It sounded like he was a little…depressed, and he wanted to go back to India,’ Durga Moparti told the station KVOR.

Moparti's husband, Rajesh Gutta, said his father-in-law had 'not been doing well' lately.

After taking part in the nuptials and posing for pictures with the beaming bride and groom, Mr Moparti told his new son-in-law he was going out for a stroll.

He was last seen at around 4pm Saturday walking at a fast pace along Grand Island Road. Neighbors say they saw Mr Moparti making his way toward a nearby bridge. He has not been seen or heard from since.

His daughter believes Moparti may have fallen unconscious and collapsed. The family are holding out hope that he will be found alive.

The newlyweds have postponed their honeymoon to San Francisco and are busy scouring the area around the mansion and handing out 'missing' posters.

‘My dad missing is the only thing going on in my head right now - nothing else,’ said Durga Moparti.

The Sacramento Sheriff's Department has launched a search for Prasad Moparti, scouring the Sacramento River by boat. A dive team and cadaver dogs are being used to help track down the missing man.

Mr Moparti is described as 5 feet 10 inches tall and weighing 180 pounds. He was last seen wearing traditional Indian dress in brown/gold colored top with a cream-colored undergarment.

Relatives say Moparti speaks English well but is not familiar with the Walnut Grove area.
