CHICAGO -- St. Louis Cardinals pitcher Darryl Kile likely died from a blockage of a coronary artery, Cook County's chief medical examiner said Sunday.

Cards to hold public service

The St. Louis Cardinals will have a tribute to pitcher Darryl Kile before Tuesday night's game, then will hold a public memorial service Wednesday at Busch Stadium. A 15-minute tribute to Kile, found dead Saturday in his hotel room in Chicago, will be held before Tuesday night's series opener against the Milwaukee Brewers. To accommodate the tribute, the first pitch was rescheduled for 7:20 p.m., Cardinals spokesman Brian Bartow said Monday. Current and past teammates of Kile's will participate in the memorial service at 12:30 p.m. CT Wednesday, Bartow said. Stadium gates will open at noon. It will be the second memorial service in a week at Busch Stadium, where longtime Cardinals broadcaster Jack Buck lay in state for a public visitation and ceremony last Thursday. As they have since hearing the news of Buck's death Tuesday night, fans continued to leave personal mementos -- signs, caps, photographs -- at Buck's statue outside the stadium. Not far down the sidewalk, fans since Saturday evening have left items at a similar shrine for Kile. -- The Associated Press

Dr. Edmund Donoghue said initial findings of an autopsy showed Kile had "80-to-90 percent narrowing of two of the three branches of the coronary artery." He said the blockage was the "likely cause of death."

Kile's heart showed no sign of scarring or heart attacks, but it was abnormally enlarged, weighing 552 grams, while about 450 grams would be normal, said Donoghue. He said that also can be caused by atherosclerosis.

Sgt. Robert Cargie, a spokesman for the Chicago Police Department, said Monday that a substance, "possibly marijuana,'' was found in Kile's hotel room the morning he was found dead. He said the substance is being tested.

Donoghue said a final autopsy report could take from 4-to-6 weeks because he still wants to study toxicology reports, and he first mentioned the existence of the substance Sunday, but he added, "I want to make it very clear it had nothing to do with his death."

Police at first denied a substance was found in Kile's hotel room, with a department spokeswoman saying Monday morning that police "reports show that there is no evidence of narcotics in the room. If there was some contraband, the police would not hold back on that. We'd have to inventory that."

Kile, 33, was found dead in the team hotel Saturday. Police said there were no signs of forced entry and no signs of foul play.

Donoghue also said Kile had dinner with his brother, Daniel, on Friday night and had complained of shoulder pain, and of feeling weak and very tired. Donoghue said in published reports that those are signs Kile might have been having heart failure.

According to the reports, the Kile brothers and some friends went to dinner Friday night before Kile retired for the evening at the team hotel at about 10:30 p.m. CT.

One of the Cardinals' physicians said Dan Kile told them on Saturday that Darryl seemed to be fine during and after their dinner.

Shoulder pain might not have been out of the ordinary for Kile, who had surgery on his right shoulder during the offseason.

The condition that caused the heart blockage, called coronary atherosclerosis, is commonly known as hardening of the arteries.

	Tough Decision For Cards
	After the unexpected death of Darryl Kile, Cards manager Tony La Russa and general manager Walt Jocketty have to make a decision under circumstances they never could have predicted. The St. Louis Post-Dispatch reported Sunday that the club will start to figure out how to replace Kile in the lineup during Monday's off day. Read more ...

Kile's father died shortly after a heart attack in his mid-40s in 1993.

Dr. Jim Loomis, the Cardinals' assistant team physician, said Saturday that the 6-foot-5 pitcher had no known health problems and was not on medication.

About two hours before Saturday's game against the Cubs was scheduled to begin, Cardinals players realized Kile was not at the ballpark and called the hotel to ask that he be checked on.

Workers at the downtown Westin Hotel forced their way into Kile's 11th-floor room because of the safety latch on the door.

Saturday's game between the Cardinals and Chicago Cubs was postponed. Later that night, the Cardinals unanimously voted at a team meeting to play Sunday night in Kile's honor. Kile had been scheduled to start Sunday.

Kile's name and No. 57 were displayed on the marquee outside Wrigley Field and on the scoreboard inside the park Sunday.

The U.S. flag was at half-mast, and all music except the national anthem was canceled. There was to be a moment of silence for Kile before the national anthem.

There were to be no public address announcements during the game except for players coming to bat and lineup changes.

The Cubs also canceled usual festivities such as honorary first pitches and the traditional singing of "Take Me Out to the Ball Game."

The Cardinals pushed back the start of Tuesday night's game against the Brewers 10 minutes to 8:20 p.m. ET so that they can show a video tribute to Darryl Kile and also have a moment of silence before the first pitch.

On Wednesday, a public memorial service will be held at Busch Stadium, starting at 12:30 p.m. CT. The current Cardinals team as well as former teammates and coaches will be present.

The Cardinals will wear a black patch with Kile's No. 57 on their left sleeve for the remainder of this season.
