Does NASA have a plan to search for the life in Europa?

ESA's JUICE mission is scheduled for launching in 2022.
One of the science objectives is the search for organic molecules near Europa.
Originally it was planned as NASA's JEO, as part of the joint mission Laplace with NASA, JAXA, Rocosmos; for details of the NASA plans see the Decadal Survey.

NASA's Juno mission is focused onto Jupiter itself, rather than on the moons.

There has been a workshop on the habitability of icy worlds in February 2014. Europa has been discussed, see e.g. this abstract.
