OAKLAND -- Police Monday released the identities of a man and woman found fatally shot Saturday in an apartment in the 1800 block of East 25th Street.

Officers responded to the area at 11:17 a.m. after receiving a phone call, notifying them that two people were dead inside the apartment, Oakland police spokesman Roland Holmgren reported.

Upon arrival, officers forced their way into the apartment and located 33-year-old William Thomas Clark Jr. and 27-year-old Leticia Thomas, both of Oakland. Holmgren said Clark and Thomas had both suffered gunshot wounds and were pronounced dead at the scene.
