STAMFORD -- A voice recognition expert testified Friday that the 911 caller who first alerted police to the homicide of Anna Lisa Raymundo on Nov. 8, 2002, was self-represented defendant Sheila Davalloo.The incriminating testimony comes on the fourth day of the Stamford murder trial in which Davalloo is defending herself against accusations she stabbed Raymundo nine times inside her Shippan condo.
Prosecution witness Tom Owen, a forensic voice identification expert, testified Friday morning that computer programs determined Davalloo placed the 911 call at 12:13 p.m. on the day Raymundo was found killed.
Owen had tried to determine who made the 911 call in 2004, but at the time his software couldn't match Davalloo with the caller's voice. Owen said he retested Davalloo's voice last year using newer, digital methods. Supervisory Assistant State's Attorney James Bernardi asked Owen whether he came to a different determination during the second test.
"Yes," Owen said. "That Sheila Davalloo is the person that made the 911 call."
Owen played the 911 call for jurors, and interspersed the statements with voice recordings made of Davalloo in January 2004. On the 911 recordings, a woman tells a call-taker that a man attacked her neighbor on Harbor View Drive. The call was made from a pay phone at a fast-foot restaurant on Shippan Avenue. Raymundo's condo was actually on Harbor Drive.
After telling jurors that Davalloo made the 911 call, Owen displayed his voice recognition software on a large television screen so the court could see how the programs objectively measure different vocal patterns. His testimony will continue into Friday afternoon.
