Mark Redwine\u2019s living room did not show evidence of a major bloodletting event after chemical testing and analysis at the home, a forensic scientist told jurors Tuesday.<\/p>\n

Richard Eikelenboom said the often-used chemical agent luminol detects traces of blood at crime scenes not perceivable to the naked eye, including after a suspect attempts to clean the scene. The chemical reacts to certain compounds in substances, like iron in blood, and creates a blue glow.<\/p>\n

But he told the jury luminol is not an entirely reliable tool because other substances, like bleach, can give off fluorescence.<\/p>\n

\u201cI think every crime scene you go to, you will find false positives,\u201d Eikelenboom said.<\/p>\n

But prosecutor Fred Johnson pointed out that further tests were completed to confirm the presence of blood at Redwine\u2019s Vallecito home, and each sample came back positive.<\/p>\n

Traces of blood were found in several locations of the living room, including on a couch cushion, love seat cushion, floor underneath a rug, rug in front of a loveseat and a coffee table. But most of those locations created small points of illumination using luminol, some as small as a dime. Those could have been the result of getting a small cut, flossing or picking a scab, Eikelenboom said.<\/p>\n
