SINTON, Texas — A South Texas man has been sentenced to life in prison for a 2012 shooting attack at a park that left one woman dead and her girlfriend critically hurt.

David Malcolm Strickland was convicted Wednesday of capital murder. The 30-year-old Strickland, who was on trial in Sinton, received an automatic life prison term because prosecutors did not seek the death penalty in the June 2012 case.

Investigators have said the two victims were sexually assaulted and shot while at a park in Portland, near Corpus Christi. Authorities say 19-year-old Mollie Olgin of Ingleside died. Her girlfriend, who was 18 at the time of the attack, was shot in the head but survived.

The victims were discovered several hours later by some people who were passing by.
