In May 2011, when Underwood was initially arraigned, his trial was supposed to be held before Sept. 22, 2011 under the terms of an interstate agreement reached between California and Essex County.
But, under the state rule concerning his right to a speedy trial, the time between court appearances can be excluded if the delay is caused or requested by the defense. This allowed Underwood to stay in the state longer.
Underwood was convicted on Dec. 19, 1997 in California for the first degree murders of Mandi Scott, 15, and Rosalie Ortega, 20, in August 1991.
His alleged ties to the Merrimack Valley and southern New Hampshire remained secret until 2011 when local detectives, using a national DNA database, matched genetic materials to samples taken from the Andover victim on May 20, 1988.
The then 24-year-old woman was driving home to Lowell on River Road in Andover when Underwood allegedly forced her car off the road, punched her in the face and ordered her at knifepoint into his truck. The woman was beaten and sexually assaulted as Underwood allegedly drove north and into southern New Hampshire. Just past the toll booths in Hampton, Underwood is accused of driving off the highway and stabbing the woman in the abdomen. The blade on his knife broke off.
Before fleeing, Underwood allegedly dumped the woman in a watery ditch. A Good Samaritan stopped and helped the woman after she managed to drag herself back near the highway.
The case was resurrected in 2009 when Andover police retrieved the woman’s rape kit from the Hampton Police Department. The samples were submitted to the Massachusetts State Police crime lab, where the DNA was submitted to the Combined Offender DNA Index System, a national database referred to by law enforcement as CODIS.
The samples matched Underwood’s DNA in the system.
