Scores of uniformed police officers were among hundreds filing into a New Orleans church to say goodbye to Daryle Holloway, an officer who was shot to death while on duty last weekend.

Saturday's viewing and memorial Mass were being held at St. Maria Goretti Church in eastern New Orleans. It comes a week after Holloway was fatally shot while transporting a prisoner.

New Orleans Mayor Mitch Landrieu, U.S. Attorney Kenneth Polite (poh-LEET') and police chief Michael Harrison were among dignitaries expected to speak at Holloway's funeral.

Meanwhile, police continue to investigate how the handcuffed suspect could have gained access to a gun, shot Holloway and escaped.

Thirty-three-year-old Travis Boys was captured last Sunday and booked with first-degree murder in Holloway's death.
