 Two men were in custody Sunday after a day-long manhunt in Wyoming in connection with the alleged kidnapping and assault of a Utah woman and her four daughters. 
 
 Dereck James "D.J." Harrison, 22, was found and arrested without incident Saturday night after the manhunt in the Half Moon Lake area northeast of Pinedale, Wyoming, police said Sunday. 
 
 His father, Flint Wayne Harrison, 51, had turned himself in to authorities in Sublette County early Saturday. At that point, he "immediately started working with local investigators to locate his son Dereck," county police said in a release.

 The Harrisons had been wanted for allegedly luring the mother and her daughters, ages 13 to 18, to a Utah home Tuesday for a barbecue. There, the men allegedly tied them up with wire and duct tape, according to police in Centerville, north of Salt Lake City. 
 
 The woman and some of the young girls were assaulted with a baseball bat as they tried to break free, Centerville police said. But the girls managed to break free and run from the house screaming for help, and one of them called 911 on her cell phone. 
 
 But by the time police arrived, the suspects had already fled. 
 
 Centerville police said Dereck Harrison was believed to have extensively used methamphetamine and may have believed — falsely, it turns out — that the woman had turned him in. 
 
 "The motive appears to be retaliation on the mother," police said Sunday. 
 
 The manhunt centered on Half Moon Lake Lodge in Pinedale, where authorities found a makeshift campsite. Authorities, who said Flint Harrison owns a home in Pinedale, evacuated the campground Saturday and urged the town's 2,000 residents to shelter in place.

 The Sublette County Sheriff's Office said the younger Harrison was believed to have been armed with two knives, a 300 Winchester Magnum rifle, a .22-caliber Remington rifle and several high-capacity magazines. Authorities said he had made several threats against law enforcement officials. 
 
 Deputies found him walking a little more than a mile from a roadblock. "This is an incredible end to a very stressful day,” Sheriff Stephen Haskell said in a statement. 
 
 Both father and son will be extradited to Utah to face charges, according to the Sublette County Sheriff's Office. 
 
 It is unclear whether they will face additional charges in Wyoming, where the elder Harrison is registered as a sex offender for attempted forcible sexual abuse in 2001, according to the Wyoming Division of Criminal Investigation. ||||| Ricks' UTA vehicle was last seen Thursday evening being driven by a man near the Ballpark Trax station, at 1300 S. 200 West, according to UTA Police Chief Fred Ross. 
 
 He said it is unknown whether the driver at that time was Ricks, but Ross "[didn't] have any reason to believe" it was someone else. 
 
 That same day, investigators said the pair of suspected kidnappers may have been at the Ramada Inn near 2400 S. State St. in South Salt Lake. The locations are about 2 miles apart. 
 
 Anyone spotting the truck is asked not to approach it, but to contact law enforcement immediately. 
 
 Ricks is described as a white male, 5 feet, 6 inches, 180 pounds, wearing a long- sleeve shirt, blue jeans and possibly a bright orange safety vest. 
 
 Sublette County sheriff's Sgt. Katherine Peterson said Monday there is no "hard evidence" linking the kidnappers to Ricks' disappearance, but Wyoming police were looking for the truck as part of their search for weapons that may have been in the Harrisons' possession. Ross said including the truck as part of the search was a way to "cover all our bases." 
 
 Meanwhile in Pinedale, Wyo., Dereck James Harrison, 22, and his father, Flint Wayne Harrison, 51, appeared in court Monday afternoon for an extradition hearing. 
 
 Both of them invoked their right to an attorney, which means there may be another hearing later this week, Peterson said. Bail was set for each man at $750,000 cash-only. 
 
 Flint Harrison had turned himself in at the jail in Pinedale on Saturday and provided information that aided deputies in narrowing down the location of his son, who was captured Saturday night. 
 
 Both men were fugitives, wanted for allegedly kidnapping and assaulting a Centerville woman and her four teenage daughters May 10. 
 
 The two Harrison men were each charged Wednesday in Utah's 2nd District Court with 10 counts of first-degree-felony aggravated kidnapping. 
 
 In another development, Maryann Dalrymple Harrison, 45 — who is Dereck Harrison's mother and the ex-wife of Flint Harrison — waived extradition and will be returned to Utah within about 10 days, Peterson said. 
 
 Maryann Harrison was arrested in Pinedale about 6 p.m. Saturday for violating terms of her parole by leaving Utah to travel to Wyoming.

 A helicopter circles as law enforcement officials work east of Highway 189 about 16 miles south of Kemmerer, Wyo., Wednesday, May 18, 2016. Law enforcement officials are looking for a possible connection between a missing Utah Transit Authority worker, whose body was discovered late Tuesday evening,... (Associated Press) 
 
 AMERICAN FORK, Utah (AP) — Utah train maintenance worker Kay Porter Ricks lived a regimented life: He went to work at the same time each day, tried to use the same service truck on his route and came home at the same hour. 
 
 The morning before he went missing last week, he even returned home to give his wife of 42 years a kiss goodbye to avoid diverting from his daily routine. 
 
 So his family knew something was amiss when the 63-year-old Mormon grandfather didn't come from work on May 12 and his truck was later spotted in Wyoming and his cellphone near a station across town, said Richard Massey, a spokesman for the family. 
 
 Their worst fears were realized Tuesday when a Wyoming sheriff's deputy found Ricks dead, wearing his work boots and jeans, some 130 miles from the spot in Salt Lake City where he was last seen checking on train tracks. 
 
 Now, the FBI and investigators in Utah and Wyoming are trying to determine if a father and son accused of holding a woman and her four teenage daughters hostage had anything to do with his death. 
 
 His cause of death has not been disclosed. But Utah Transit Authority Police Chief Fred Ross said it has been ruled a homicide. 
 
 Police have not definitively linked Flint Wayne Harrison, 51, and his son Dereck James "DJ" Harrison, 22, to Ricks' death. 
 
 "There are some coincidences there that would be impossible to ignore as we continue to investigate," Lincoln County Sheriff Shane Johnson told the Deseret News. 
 
 Ricks vanished during his night shift a few miles from a Utah house where investigators believe the father and son had been lying low before heading to Wyoming. Ricks' body was found in the same Wyoming county where his work truck was last spotted by surveillance cameras. The county borders the area where the Harrisons were camping before their weekend arrest. 
 
 The missing truck could explain how the Harrisons traveled nearly 250 miles from Utah to Wyoming, authorities said. 
 
 The deputy who found Ricks was taking one last look after the search had officially ended for the night when he noticed Ricks' boots, Massey said. His body was discovered near a dirt road about 16 miles south of the town of Kemmerer, Wyoming, said Lincoln County Sheriff Shane Johnson. 
 
 Authorities still haven't found Ricks' truck but vowed to keep searching. 
 
 Massey said authorities haven't told the Ricks family about finding any evidence connecting his disappearance to the Harrisons. He said Ricks' family members who live in the small city of American Fork south of Salt Lake City, are mourning their loss rather than speculating on what happened. Ricks had three grown sons and six grandchildren. 
 
 "The fact that something nefarious may have happened to cause Kay to lose his life is really not the family's focus," said Massey. "There are six grandchildren that greatly miss their grandfather. As you can well imagine, it's difficult explaining to them what has happened to their grandfather." 
 
 The FBI is assisting authorities, but spokeswoman Sandra Yi Barker couldn't provide any more details 
 
 The Harrisons were arrested over the weekend after a five-day search. The father eventually surrendered and led police to the remote camp near Pinedale, Wyoming. 
 
 The two are accused of using drugs and tying up a woman and her four teenage daughters in a basement on May 10 because they wrongly thought the mother had reported them to authorities. The family was able to break free and escape. 
 
 The Harrisons will be extradited to Utah to face 16 charges each, including kidnapping and drug possession. They are not talking to police, Centerville, Utah, police Lt. Von Steenblik said.

– A 22-year-old man and his parents have been arrested after the alleged abduction of a woman in Utah and her four teen daughters. The latter five managed to escape and alert authorities, reports NBC News. Police say Dereck Harrison, 22, and his father, Flint Harrison, 51, knew the Utah mother and suspected her of telling authorities about their drug use. They lured her and her daughters, ages 13 to 18, to a home on the pretext of a barbecue, then tied all five up with zip ties, say police. The elder Harrison hit the mother with a baseball bat, at which point the daughters began breaking free from their ties, say the charging documents, per the Casper Tribune. One of the girls knocked away a shotgun pointed at her throat and another seized the bat and hit the younger Harrison with it, say police. The victims fled, as did the Harrisons, but both suspects eventually surrendered separately in Wyoming and now face charges of aggravated kidnapping and possession of a controlled substance. While Dereck Harrison was still on the loose, his mother, Maryann Dalrymple Harrison, went to police in Wyoming to obtain information about her son, but she, too, ended up under arrest. It seems she violated her probation by leaving Utah without permission. (No more details were provided on her case.) Police say that the victims are recovering but that the Harrisons aren't cooperating with the investigation.
