The body of an LDS missionary from Bountiful who was shot and killed in Virginia is expected to arrive in Utah today, and his funeral is set for next week.

Meanwhile, police in Virginia arrested a 19-year-old man late Wednesday and charged him in the slaying.

The funeral for Elder Morgan Winslow Young, 21, is scheduled for noon Tuesday in Bountiful. His parents are expected to address the media for the first time this morning.

Young and Elder Joshua Heidbrink, 19, of Greeley, Colo., were going door-to-door in Chesapeake, Va., proselyting for The Church of Jesus Christ of Latter-day Saints on Monday when they were both shot by a man who had confronted them. The assailant then ran off.

Wednesday night, Chesapeake police issued an arrest warrant for 19-year-old James Rickey Boughton Jr. He was arrested at his home at 11:45 p.m. without incident, said officer Christina Golden.

Boughton lives in a subdivision called Camelot, which is relatively close to where the shootings occurred, according to Golden.

He was arrested and charged with first-degree murder, malicious wounding, attempted malicious wounding and three counts of illegal use of a firearm. An arraignment scheduled for Thursday was continued until Jan. 20. Boughton was in the Chesapeake City Jail Thursday without bail.

Investigators Thursday were still not releasing details of a possible motive for the shootings other than to say they believed the missionaries witnessed a crime in progress, according to Golden. Police had said earlier that they did not believe the shootings were a hate crime.

Investigators were also not saying Thursday what kind of crime they believe the missionaries may have witnessed.

Golden said a "combination of things" led to Boughton's arrest. One piece of evidence that may have been key was the recovery of the gun police believe was used in the shootings.

She added that detectives do not want to release many details yet because the case is still active and additional arrests are possible, although she did not know if those arrests would be in relation to the homicide.

A check of Virginia court records showed Boughton was charged with DUI in August and cocaine possession in May. A preliminary hearing on the cocaine charge had been scheduled for today.

As police in Virginia were making the arrest, Young's parents were already on their way back to Utah.

Young's grandfather, Winslow Young, 69, picked up Morgan's parents, Mark W. Young and Kathy Young, about 1:30 a.m. Thursday at Salt Lake City International Airport.

"They were utterly exhausted. I mean they were really, really tired and just drained," he said.
