Police cordoned off at least four separate locations on the streets surrounding the initial discovery. There were uncollected trash and recycling piles throughout the area, and white sheets covered items near the piles in at least two spots.
Witnesses said the sheets were placed shortly before children and parents started walking through the neighborhood to reach a public elementary school.
Police interviewed witnesses and also were talking to the victim's son. Some witnesses told police an SUV dropped the bags off sometime during the night.
