WESTERVILLE, Ohio (WCMH) — A man has been charged with murder and endangering children after allegedly causing life-threatening injuries to his 4-month-old daughter.

Joseph S. Blair, 22, of Westerville, was arrested after he reportedly tripped while holding the infant, causing her to hit her head, become unconscious and sustain “serious physical harm,” according to records from Franklin County Municipal Court.

Westerville police said Thursday that Blair’s charges were updated to murder and endangering children after Janiya Cochran-Blair died from her injuries.

Blair took nearly two hours before bringing her to St. Ann’s Hospital, court records state.

Although Blair said he tripped, causing her to hit her head on the corner of a couch, court records said he changed his story multiple times. Physicians at St. Ann’s and Nationwide Children’s Hospital said the injuries did not match Blair’s explanation.

Blair is due to appear in court on Monday.
