South County-based Missouri state Rep. Genise Montecillo has decided not to run for re-election.

Montecillo, D-Marlborough, announced Friday she's dropping out of the race after the Aug. 2 primary. She'll remain in office for the short September session and through the rest of her term, which ends in January. The announcement said she will return to her pre-legislative career of teaching.

Montecillo is a three-term lawmaker who was first elected in 2010. She represents the Affton area in South St. Louis County.

Montecillo attempted suicide last year, and subsequently made suicide prevention and awareness a centerpiece of her legislative work.

In an emotional speech on the House floor months later, in support of measures to require school districts to adopt policies on suicide awareness and prevention, she told her legislative colleagues that her suicide attempt was rooted in emotional abuse at the hands of her late mother.
