While investigators continued Saturday to scour the scene of last week's quadruple homicide in Aurora, a relative of the people killed still was being questioned in Wisconsin.
The 28-year-old Naperville man, who on Friday was spotted by a Wisconsin state trooper as he drove north on Interstate Highway 90/94, remains in custody in Columbia County Jail and has been questioned by DuPage County authorities. He has not been charged.
Meanwhile, a close friend of one of the four victims said the man in custody had money problems and had argued with the family recently.
Margaret Brown, 35, said that she met Jimmy Tsao seven years ago and that the two had been close friends since.
Brown last saw Tsao Tuesday night when they had dinner together at an Aurora restaurant.
There, Tsao complained of the difficulties he, his wife and her parents had with the relative in custody. The man recently had charged about $10,000 on the Hansons' credit card, she recalled him saying.
A few years ago, Kate Tsao confronted the relative about taking $2,000 from their bedroom, she remembers Tsao saying. Because of the incident, Tsao would not allow the relative in his home.
"He was always trouble," Brown said of the relative, whom she said she had met before. "It was always about money -- either him asking for it or him taking it."
