Actress Delia Razon successfully urged the head of LVN Pictures, Doña Sisang de Leon to hire Blanca.

[1] She was screen tested on October 6, 1951, by LVN Pictures where she reigned as "queen" of movies for more than a decade, doing mostly comedies opposite the late Nestor de Villa.

She also starred in the hit TV comedy series, John en Marsha, where she played the wife who sticks by her poor husband despite her rich mother's constant harping.

In 1958, she appeared opposite her contemporary, noted singer/actress Sylvia La Torre, and Leroy Salvador, in the LVN movie Tuloy ang Ligaya.

She later married her second husband Roger Lawrence Strunk (1939-2007) an American singer and actor, known by his screen name Rod Lauren in Las Vegas in 1979.

[2] The case rested on the statements of witnesses and Philip Medel, a self-confessed killer who surrendered to PNP Task Force Marsha on November 19, 2001, and confessed that Strunk had hired him to kill Blanca.

[3] Despite Medel's recantation, Strunk remained the prime suspect according to Philippine prosecutors, based largely on circumstantial evidence and statements of new witnesses.
