We have them in headlines almost weekly: An older person, perhaps confused, who was slow getting back from an errand. An angry high school student who hid out at a friend’s house. Amber Alerts stemming from custody disputes or worse.

Mostly, those missing-persons cases are resolved quickly. But Pennsylvania has more than 400 open cases involving people missing – some for decades – according to a study released this month.

According to VivintSource.com, there are about 407 open cases as of this week, making Pennsylvania the 10th highest in the country. Missing simply means their whereabouts are unknown, whether they’ve gone voluntarily or against their will.

Following are the two dozen open cases reported from central Pennsylvania. The ages listed are as of the time of disappearance; the youngest is 4, the oldest 68. The cases date from 1961 to 2018.
