A Nebraska priest has died after being attacked in the rectory of his parish in the early morning before he was to celebrate Mass for the Second Sunday of Advent.

Father Stephen Gutgsell was found "suffering from injuries sustained during an assault" on Dec. 10 at the rectory of St. John the Baptist Catholic Church in Fort Calhoun, Nebraska, where he served as pastoral administrator.

According to a Dec. 10 press release from the Washington County Sheriff Mike Robinson, the county's 911 emergency dispatch received an emergency call Dec. 10 at approximately 5:05 a.m. reporting an attempted break-in at the rectory. According to the statement, deputies arrived within six minutes and found the suspect — later identified as Kierre Williams — inside the residence with the injured priest.

Father Gutgsell was transported to the University of Nebraska Medical Center in Omaha, Nebraska, where he later died.

Williams, a 43-year-old man from Sioux City, Iowa, was taken into custody and booked on charges of homicide and use of a weapon to commit a felony.

The Washington County Sheriff's Office said the case is in the hands of the county attorney.

In 2007, Father Gutgsell pleaded guilty to embezzling at least $125,000 from St. Patrick Church in Omaha. He was sentenced to five years of probation and ordered to pay back the funds. After completing a residential treatment program, the Archdiocese of Omaha then assigned him to assist with Blessed Sacrament Parish, now part of St. Philip Neri Parish, in Omaha, with the pastor of St. Philip Neri placed in charge of parish finances.

In June, Father Gutgsell's brother, Father Michael Gutgsell -- who served as chancellor of the Archdiocese of Omaha from 1994 to 2003, and as pastor of several parishes thereafter -- pleaded guilty to stealing $155,000 from Father Ted Richling, an elderly priest for whom he served as power of attorney. He was placed on two years of probation. Father Michael Gutgsell was also charged with stealing more than $96,000 from St. Joseph Parish in Springfield, Nebraska, of which he had been pastor. Those charges were dropped in return for repaying the funds.

Robinson told local media that he did not believe Father Stephen Gutgsell's death was related to the priest's prior offense.

In a statement posted to its website, the Archdiocese of Omaha said it is "praying for Father Stephen Gutgsell" and that with the investigation in progress "there are no further details at this time.

"Please join Archbishop George Lucas in prayer for the repose of Father Gutgsell, for his family and for the St. John the Baptist parish community in this tragic time.”

Local media reported that tributes poured in at a vigil held that Sunday, with parishioners mourning a priest known as a "wonderful person" and "brilliant man" who held Bible studies, loved to see the altar decorated with flowers, and was known for devoting himself to the needs of others.

According to the archdiocesan website, Father Gutgsell served as both St. John the Baptist's pastoral administrator and chaplain of the Madonna Rehabilitation Hospitals in Omaha, Nebraska, which provide care for brain and spinal cord injuries as well as complex medical conditions.

Father Stephen Gutgsell's final message in the bulletin to his flock concerned the patron saint of their parish, noting the Second Sunday of Advent -- the Mass he was supposed to celebrate that day -- could be called "St. John the Baptist Sunday" with its theme "Prepare the way of the Lord."

The priest noted the prophet who told others about "Jesus as Lamb of God" himself was "a great man whose life was cut short by the spite of (a) non-queen and the drunken promise of a non-king" after the dance of a young woman "who was not a princess."

"John is 'the Voice of one crying out ... Prepare the way of the Lord, make straight his paths.' As the Fathers of the Church described him, he is the Voice who announces the coming of the Word, who was God from the beginning and has now become Flesh in order to dwell among us," the priest wrote. "As Christmas draws near, the voice of John the Baptist is meant to remind us of what we all should be preparing to receive in the Advent Season. God bless you and your Family in this Wonderful Season of Grace."
