Who wrote the Dead Sea Scrolls?

From Live Science:

The Dead Sea Scrolls may have been written, at least in part, by a sectarian group called the Essenes, according to nearly 200 textiles discovered in caves at Qumran, in the West Bank, where the religious texts had been stored. Scholars are divided about who authored the Dead Sea Scrolls and how the texts got to Qumran, and so the new finding could help clear up this long-standing mystery.

The research reveals that all the textiles were made of linen, rather than wool, which was the preferred textile used in ancient Israel. Also they lack decoration, some actually being bleached white, even though fabrics from the period often have vivid colours. Altogether, researchers say these finds suggest that the Essenes, an ancient Jewish sect, "penned" some of the scrolls.....

Scholars are divided about who authored the Dead Sea Scrolls and how the texts got to Qumran. Some argue that the scrolls were written at the site itself while others say they were written in Jerusalem or elsewhere in Israel….

More recent archaeological work....suggests that the site could not have supported more than a few dozen people and had nothing to do with the scrolls themselves. They believe that the scrolls were deposited in the caves by refugees fleeing the Roman army after Jerusalem was conquered in A.D. 70.
