Karen Read CSLI Maps — Cell Tower Connection Visualizations
Maps of Read's phone connections to cell-tower antennas from about 12:33 to 6:57 a.m., including tower 5721 relative to 34 Fairview and 12 Country Lane.
About
The prosecution argued the maps narrowed Read's phone location to specific geographic arcs corroborating surveillance video timestamps. The defense used the tower 5721 distance data — approximately 1 mile from McCabe's residence versus 2.4 miles from 34 Fairview — to suggest Read's 5:20–5:37 a.m. phone activity was closer to McCabe's house than to the crime scene.
