A "person of interest" has been identified and is reportedly in police custody in the Thursday killing of a 14-year-old southwest suburban girl.
Kelli O'Laughlin, a freshman at Lyons Township High School, was found by her mother in their home in the 6300 block of Keokuk Road in Indian Head Park. She was declared dead shortly thereafter at a hospital nearby.
Police told reporters Friday afternoon that Kelli may have been confronted by a burglar when she walked into the home after school Thursday afternoon. A source told the Chicago Sun-Times that the man was a stranger to Kelli. He apparently killed the teen when she thwarted his burglary attempt.
It is believed to be the first murder in the town's history, according to the Sun-Times.
Hundreds of students, parents and community members gathered to mourn and celebrate Kelli's life at a tearful candlelight vigil at Lyons Township High School's South Campus Friday evening, Patch reports.

One friend described Kelli as "just a sweetheart," according to the Chicago Tribune. Another classmate who knew her described her as "so friendly and easy to talk to -- always nice to everyone. She was outgoing and happy."
Earlier in the day, groups of students at the Western Springs school tied white ribbons around trees, "white, because white is pure, just like Kelli," according to one friend of the slain girl. Other students wore purple ribbons around their heads Friday, because "purple was her favorite color."
A spokesperson for the Cook County Medical Examiner's Office said Kelli's cause of death was "multiple stabs and incised [knife-like] wounds." The suspect has been described, based on a witness description, as a black male with a dark complexion, 30-35 years old, between 5-foot-8 and 5-foot-9 with a medium build. He was reportedly seen in the Indian Head Park area wearing a dark hoodie and carrying a patterned backpack.
An anonymous donor has offered a $10,000 reward for anyone who offers information leading to an arrest and conviction in the killing, NBC Chicago reports.
Earlier in the year, the area played host to a spate of burglaries where a man reportedly used Google Maps' "street view" to identify upscale suburban homes and survey their properties in order to plan his break-ins.
