A white, male cop in Fort Worth, Texas, is on leave after he fatally shot a black woman in her own home early Saturday. CBS News reports that the unnamed cop was sent to Atatiana Jefferson's home after a concerned neighbor called a non-emergency 311 number around 2:25 a.m. because her front door was ajar and he knew she was home with her 8-year-old nephew. CNN reports that the responding officer's bodycam footage indicates he shouted commands outside the 28-year-old's residence before firing into a window of what looks like a darkened room just two seconds later. "A young woman has lost her life, leaving her family in unbelievable grief," Fort Worth Mayor Betsy Price said in a statement. "All of Fort Worth must surround Atatiana Jefferson's family with prayers, love and support." Price also promised a "complete and thorough investigation." Jefferson's death comes less than a month after white Dallas cop Amber Guyger was sentenced to 10 years in prison for fatally shooting her black neighbor, Botham Jean, after mistaking his apartment for hers.
