PFLUGERVILLE, TEXAS: A former football player from the University of Texas at San Antonio, arrested for the murder of his pregnant sister, could be heard confessing to killing her on a video recorded moments after her death.

Michael Egwaugu, 25, admitted he murdered his elder sister Jennifer Ebichi, 32, and says "I killed Jennifer" in video captured by a doorbell camera installed in her Pflugerville home, according to an arrest affidavit obtained by the Austin Statesman.

Police had rushed to Jennifer's home, located on the 16000 Block of Vescovo Lane, on December 27, after Michael's twin brother Martin alerted them to a threatening situation developing.

He told cops that he had received a text message from Jennifer around 5:30 am stating that his brother was "at the residence and was having a crisis." Martin said he tried to speak to Michael and calm him down but was alarmed when the latter made several strange statements.

Martin said he received another text from Jennifer around 4:10 pm asking him to come to the house, and that when he arrived, he saw a woman he recognized as a member of his church standing on the front lawn with his sister's oldest child covered in blood.

When he went inside the residence, Martin found Jennifer lying in a pool of blood on the kitchen floor. She had suffered one to two dozen stab wounds. He also heard her youngest child crying and took the kid out of the house.

Martin told police that when he went outside, he found Michael Egwaugu in the street kneeling as if praying. He then got up, removed his bloody clothes and placed them in a trash can along the curb.

When deputies arrived, the woman told them that Jennifer had asked her to come and that she heard Jennifer, her children and Michael screaming and yelling inside the house. Soon, she saw Michael exit the home smiling and holding a bloody kitchen knife.

An autopsy conducted on Jennifer Ebichi found that she was in the first trimester of her pregnancy. 

Michael Egwaugu was arrested and charged with murder on Friday night and is currently being held at the Travis County jail on a $500,000 bond.
