A man authorities in Boone County, AR, have been searching for as "a person of interest" for his alleged connection to the murder of his girlfriend near Omaha on Tuesday has been apprehended in Missouri.

Working on a tip, authorities in Stone County started watching the Shoal Motel near a local campground where they believed Ernest Doyle Chastain Jr, was holed up in.

Stone County Chief Deputy Quirt Page says his office got a call from a the manager of the motel who was alerted by a guest who thought another guest could be the man authorities were looking for after watching the 10 p.m. news.

Quirt says that deputies waited until daylight in a room right in front of a red Isuzu S-U-V with Arkansas plates.

Their wait paid off....a little after 7 a.m. Chastain was taken into custody as he walked toward the S-U-V that was stolen when 53 year-old Susan Powers was shot to death in her home.Chastain and a woman who was in the motel room were taken into custody without incident.

Quirt says the woman really didn't know Chastain, "we determined that she was someone he picked up in Taney County. Quirt added that the woman, "was pretty surprised and shocked," after authorities questioned her. Once they determined that the woman had no role in Powers death she was released.

Chastain waived extradition and was released to Boone County Arkansas authorities for transfer to their facilities.

Boone County Chief Deputy Prosecutor Wes Bradford says a murder warrant was issued against Chastain, but it had not been returned to the circuit clerks office as of 3:30 p.m.

Bradford says, "I believe he will be arraigned on charges sometime tomorrow."

Search warrants were served on the motel room and the S-U-V Chastain was driving for any possible evidence that could be connected to the homicide.
