Biography
Lorenzo Pinero was a leader of the Puerto Rican Nationalist Party prosecuted in 1937 in the wave of repression around the 21 March 1937 Ponce Massacre, when police fired on a Palm Sunday march at Ponce, killing some twenty and wounding hundreds; the ILD defended the jailed Nationalists.
The September 21, 1937 New Masses editorial individually lists this defendant among ten Nationalists then facing the Ponce murder trial and reports that the group had been imprisoned for six months in La Princesa under collective bail totaling $250,000. This is a contemporary approximate custody-to-date report, not a completed six-month sentence, exact admission date, individual bail amount or final conviction. Its description of a hand-picked jury and government campaign is the editorial’s allegation. The existing prosecution is retained without a duplicate case.

Dávila Marichal identifies Lorenzo Piñeiro among those prosecuted after the Ponce massacre and reports total acquittal of the Nationalist defendants after a three-month trial. The trial length is not a custody total, and acquittal is not converted into an exact release day.
