TULSA, Okla. - Two children, a man and a woman, were found shot to death inside at an apartment complex in an apparent murder-suicide, police said.
Just after 12:30 a.m., police in Tulsa found a 22-year-old woman, a 5-year-old girl and a 3-year-old boy. All three had gunshot wounds and were deceased.
Police said a 35-year-old man, the woman's estranged husband, shot the three victims before killing himself.
According to investigators, the woman left the two children with their father earlier in the day and brought her roommate's child with her to pick up the children. It was at that time the shooting occurred.
The surviving child was inside the apartment at the time of the shooting but was not harmed and has been reunited with her mother, KJRH reported.
Police say the suspect was living at the apartment with two other men who were not present during the shootings. The bodies were discovered when one of the men returned home.
Detectives said it appears the suspect took the victims by surprise just moments before the shooting occurred.
According to police reports, all the victims were from Guatemala with no next-of-kin living in the United States.
