(JEFFERSON CITY)--The number of those held in Missouri as sexually violent predators is rising.

As a result, mental health officials are seeking millions of additional dollars for their care and treatment, and Governor Jay Nixon has recommended more than $2.6 million for nearly 60 additional positions at two Missouri state health hospitals.

A 1999 Missouri law permits certain sex offenders to become committed after completing their criminal sentences if they are "more likely than not" to commit sexual violence upon release.
