To James Vernon McVay, who was arrested Saturday after a police chase on Interstate 90 near Madison, killing 75-year-old Maybelle Schein in South Dakota was the first step in a long-pondered plan to kill President Obama, according to South Dakota court records.

In a criminal complaint filed Tuesday, charging McVay with murder for the death of the hospice nurse Saturday in her Sioux Falls home, McVay told Madison police that he intended to kill somebody in Madison and steal their car, ambush a Madison police officer and take the officer's guns and kill and steal cars again in Chicago and Indianapolis.

Then he would use a rifle to kill the president.

"I'm going to kill and kill until I get him," McVay said, according to the complaint.

McVay, 41, was driving Schein's 2007 Buick Lucerne about 6 p.m. when it was tracked to the Madison area using the car's on-board OnStar satellite assistance service.

Madison police, along with Dane County deputies and the State Patrol, used spike strips to stop McVay about 6:50 p.m. after a chase on I-90. As he sat in the back seat of a Madison squad car, McVay admitted that he had "killed an old lady" by stabbing her, the complaint states.

But that was to be just the beginning. According to the complaint:

McVay said he started "solidifying" his plan to kill Obama about two weeks ago, when he learned he was to be released on parole from the South Dakota State Penitentiary.

McVay said he needed to "get blood on (his) hands" and "get experience" killing people. He said he wanted to go to affluent areas of Sioux Falls to where the "high and mighty Christians" lived to prove to them that they were "not invincible."

McVay was released to the Community Transition Program on June 30 and walked away from it the next day. He walked to a Walmart store in Sioux Falls and stole items including camping knives and clothing.

McVay slept under a bridge that night and in the morning found Schein's home, with the garage door open about a foot. She was asleep, he said, and he could have taken her purse and walked out but "I didn't want to."

McVay said he stood by Schein until she woke up, then began stabbing her and cut her throat.

McVay was charged with premeditated first-degree murder and a separate first-degree murder charge. Both are punishable by death under South Dakota law but McVay can only be convicted of one or the other. He was also charged with two counts of armed burglary and two counts of burglary while inflicting injury on another.

According to the Sioux Falls Argus-Leader, Schein worked the night shift as a nurse at a Sioux Falls hospice for the past 15 years. She grew up in South Dakota but traveled the world during her career with the Centers for Disease Control and Prevention in Atlanta before returning to South Dakota.
