Grand County investigators hoped Wednesday that an interview with a homicide suspect being held in Kansas would provide information on the murder last weekend of a Thompson Springs woman.

Sheriff Jim Nyland and investigating officer John McGann were scheduled Wednesday afternoon to interview Phillip Jablonski, 45, current address unknown. Jablonski was arrested on a warrant Sunday in McPherson County, Kan., for questioning in two homicides out of California.Sgt. Doug Squire said the gun used in the fatal shooting last Saturday of Margie Rogers may be the same weapon used in the California slayings.

Investigators say Rogers, 58, was shot twice with a .22-caliber gun about 7:15 a.m. April 27 during a robbery at the Rogers Roost gas station and convenience store in northeast Grand County. Nyland said the killer apparently went into the store for coffee, approached the counter, shot the woman at close range and made off with about $100.

A memorial service for Rogers was conducted Tuesday in Moab at the Old City Park.

Kathy Willard, a dispatcher in McPherson County, said Jablonski was southbound on I-135 when he was arrested by a highway patrolman Sunday evening.

Willard said trooper John Smith had pulled into a rest area to check on Jablonski's vehicle, which had its hood up. She said the officer ran a check on the car tag. "It came back `wanted.' "

She said the trooper let the motorist pull away and called for assistance.

Jablonski waived extradition proceedings Tuesday in McPherson County District Court, which means he will be transported to California within 10 days, Willard said.
