The sister of William Wade Bicknell has been arrested in connection with the convicted murderer's escape from custody.

Sandra Lynn Myshak, 47, was arrested in Edmonton on Friday on allegations that she "aided and abetted" her 42-year-old brother in his escape on Thursday.

Bicknell overpowered a guard and took him hostage. Bicknell was serving a prison term for the second-degree murder of a woman from Maple Ridge, B.C.

Sgt. Tim Taniguchi, speaking on behalf of Alberta RCMP, said that Bicknell visited his sister on a day pass on Friday.

"The investigation has revealed that she was visited by him earlier in the day while on a temporary absence from the Drumheller Correctional Institution," Taniguchi said.

"She is facing seven criminal charges including assisting in escaping custody, assisting a person unlawfully at large, aiding in kidnapping with a firearm, aiding in robbery with a firearm, aiding in pointing a firearm, and aiding in break and enter to a dwelling house to commit an indictable offence," he said.

Myshak will appear in Edmonton provincial court on Tuesday.

Armed and dangerous

Taniguchi wants to remind the public that Bicknell's whereabouts are unknown and that he is considered to be armed and dangerous.

The rundown

William Wade Bicknell, 42, is 6'6" and weighs 400 pounds.

He has brown hair and hazel eyes with a fair complexion.

He has a number of tattoos including full sleeves on both arms, a unicorn on his left shoulder, a cobra on his left arm, and a heart on his chest.

Police received a call at 8:00 p.m. MT Thursday after Bickell overpowered the guard and gained control of the vehicle that was taking him back to Drumheller from Edmonton.

Bicknell took the guard hostage and returned to Edmonton, where Bicknell allegedly obtained several firearms as well as ammunition, police said Friday.

The two then travelled to a rural residence in the Chipman area, northeast of Edmonton, where Bicknell forced his way in and forcefully took vehicle keys from the homeowner.

Before leaving the residence, Bicknell disabled the telephone and the Correctional Services vehicle and told both individuals not to call police.

Bicknell fled the home in a 2009 grey Chevrolet Impala with Alberta licence plate CXE - 602. RCMP believe Bicknell knew the homeowner, and neither the homeowner nor the corrections employee was injured.

A brutal killing

Bicknell was convicted in 2003 of killing Angela Steer, 37, in her home in Maple Ridge, B.C., on April 11, 2001.

Steer died of blunt force trauma to the head. During his 2003 trial, Bicknell claimed he was acting in self-defence when he struck her with a baseball bat because she had hit him first.

Bicknell and Steer had been arguing over a bank machine fraud where he would deposit empty envelopes purporting to be cheques and then try to withdraw cash.

Bicknell dumped Steer's body over an embankment outside Mission, B.C.

Her remains were found by a fisherman six days later.
