The growing number of DNA identifications of missing people (and criminals) gets well-deserved attention. But another set of technologies is also locating more and more people who disappeared mysteriously -- underwater searches using sonar, remotely operated underwater robots and divers. In some cases, overwater searches by drones are also locating these people.

These cases often involve people who were last known to have been driving somewhere, then disappeared along with their vehicles. Many of the discoveries are being made by volunteers, from well-organized groups to individuals "fishing" with magnets.

Erin Foster, 18, and Jeremy Bechtel, 17, in Tennessee (2021)"But for years (since their 2020 disappearance), no new evidence has emerged in the case. That all changed in November when YouTuber Jeremy Beau Sides made a grim discovery, a 1998 Pontiac Pontiac Grand Am sitting at the bottom of Calfkiller River in Sparta, cops said."

"The body pulled from a car in a Florida pond has been identified as the missing mom who vanished while doing errands, authorities said."

"Heather Bloom was last seen in the care by her sister, Shari Bloom, who resides in Berkeley, California. Heather has not been seen since 2005. Heather has down syndrome and may be seen in a wheelchair. Heather is non-verbal and requires constant care and daily medication for a thyroid condition:" NAMUS.

"The police went to Shari's new apartment in March 2010 and she wouldn't open the door for them. She answered questions through the window and said Heather was fine, but she refused to let anyone see Heather or come inside the home:" Charley Project.
