Detectives suspect a man charged with a 16-year-old Missouri City murder may be a serial killer.
Thirty-three-year-old Edward George McGregor is charged in the April 1990 death of Kim Wildman.
Houston police investigating the slayings of two single mothers found strangled and beaten within months of each other also have focused on McGregor.
Police say the Houston victims, 28-year-old Danielle Subjects and 25-year-old Mandy R. Rubin knew McGregor.
Aside from Texas, investigators say McGregor has lived in Florida, Georgia and Louisiana. That also has detectives combing through files of unsolved cases, looking for other possible victims.
