The Oceanside Police Department is asking for the public's help in locating a woman who has been out of contact with her family for more than 30 years.

Yvonne Martinez was last heard from by relatives in 1993, according to authorities. Family members report they have received no communication from her since that time, despite her close relationship with her children and grandchildren.

Investigators say Martinez was known to take trips internationally, including destinations in South America and the South Pacific. She also resided in multiple locations throughout the United States over the years.

Anyone with information about Martinez's whereabouts is urged to contact the Oceanside Police Department's Missing Persons Unit at (760) 435-4846.
