A TWIST IN THE MYSTERY OF WHO OWNS THOSE HEIGHTS HOLDOUT HOUSE BONES Maybe you were expecting DNA testing to identify those human remains — found inside the wall of a Heights bungalow on Allston St.  — as those of Mary Cerruti, the missing 61-year-old woman who refused to let Trammell Crow annex her home as part of the Alexan Heights apartment complex the developer built on the block. After sending one of the recovered teeth to the University of North Texas last year to compare it to DNA samples from 3 of Cerruti’s relatives, the results are in — and there’s no exact match, reports Emily Foxhall. The Harris County Institute of Forensic Sciences is still working to see if there’s any connection between Cerruti and skeleton left behind at 610 Allston, but according to a spokesperson, further study will take “a lengthy period of time.” [Houston Chronicle; previously on Swamplot] Photo: HAR
