Former Hewlett-Packard investigators to be sentenced in federal court

SAN JOSE, Calif. - Two former private investigators are facing sentencing on charges of allegedly using false identities to gain access to the phone records of Hewlett-Packard board members, employees and journalists.

Matthew DePante and his father, Joseph DePante, are to appear in U.S. District Court in San Jose today, each to be sentenced to three years of probation and six months of electronic monitoring as part of a deal with prosecutors.

Both men pleaded guilty to conspiracy to commit Social Security fraud in February.

Federal prosecutors said the Silicon Valley tech giant had hired the DePantes' Florida-based investigation firm, Action Research Group, to track down who was leaking boardroom information to journalists starting in 2005.
