OKLAHOMA CITY - Oklahoma County prosecutors have filed a first-degree murder charge against 22-year-old Isaiah Tryon for the death of Tia Bloomer on March 16.

Witnesses say Tryon approached Bloomer, 19, at the Metro Bus Station at 420 N.W. 5th Street. Bloomer reportedly told Tryon to leave her alone. Witnesses say that's when Tryon pulled out a knife and stabbed Bloomer several times.

Bloomer was rushed to the hospital, but was declared dead soon after she arrived. A security officer at the bus station took Tryon into custody and held him until police arrived.
