The boy's suspected motive was escape, having reportedly fled from a burglary scene late Wednesday morning.
A teen is being held in connection with the death of a well-liked Indiana special education teacher, police said.
The 16-year-old boy was arrested late Thursday night, one day after Anna Schulz was found dead in her Merrillville, Ind., home, the Post-Tribune reported.
The teen, whose name was withheld because formal charges have yet to be filed, had no prior contact with the Lew Wallace High School teacher, police said. He's being held in the Lake County (Indiana) Jail.
Schulz, 80, was found laying on the ground in her nightgown and with rollers in her hair by her son. Her 2003 silver Cadillac DeVille had been stolen.
Merrillville police Lt. Jeff Snemis said the slaying and vehicle theft may have been part of a hurried escape attempt. The teen had reportedly been chased on foot earlier Wednesday, a suspect in another burglary in the area.
Schulz's car was later found in a Gary alley, near the home of one of the teen's relatives, police said, according to the Post-Tribune. Relatives then helped authorities find the teen.
