More information is coming out about the tragic death of Olympic sprinter Oscar Pistorius's model girlfriend, Reeva Steenkamp.

Oscar — the 26-year-old runner who made history as a double-amputee in the Olympics — wept in court in South Africa as he was charged on February 15 with murder.

Prosecutors say they'll pursue an upgraded charge of premeditated murder, which carries a lifetime prison sentence.

According to reports, 30-year-old Reeva was shot through a bathroom door. She was shot four times, with bullets hitting her head, chest, hand, and pelvis.

Police were apparently called to his home home two hours before the shooting, as neighbors had reported hearing an argument.

In a statement, Oscar says he sends "his deepest sympathies to the family of Reeva."

His ex-girlfriend Jenna Edkins wrote on Twitter, "I have dated Oscar on and off for 5 YEARS, NOT ONCE has he EVER lifted a finger to me or made me fear for my life."

Our thoughts are with Reeva's family.
