DEDHAM, Mass. (AP) – A former State Police sergeant accused of stealing and selling cocaine and abusing his wife was convicted Tuesday of misdemeanor assault charges, but a jury found him innocent of other charges and failed to reach verdicts on more serious drug charges.

Prosecutors said they plan to retry Timothy White on five charges that include cocaine trafficking and marijuana distribution.

A Norfolk Superior Court jury deliberated for about a week before it convicted White of assaulting his wife, Maura, on two occasions – slapping her once in 2003 and throwing her against a wall in 2002.

White, 42, was scheduled to be sentenced Wednesday on those two misdemeanor charges, which carry a maximum of two-and-a-half years in jail.

White’s attorney, Robert George, said he will ask Judge Judith Fabricant to sentence his client to the two years and five months he already has served behind bars.

White is accused of stealing up to 27 pounds of cocaine from a State Police locker. The former State Police spokesman and his wife allegedly teamed up with two others to sell the cocaine, beginning in 2002. Maura White was granted immunity from prosecution in return for testifying against her husband.

White was arrested in 2003 on charges he held a gun to his wife’s head during a stand-off with police at their home. The jury cleared him of five charges, including attempted murder and distribution of the drug Ecstasy.

George said the failure to win a conviction on the drug charges is a “political embarrassment” for Attorney General Thomas Reilly’s office, which is prosecuting the case.

“They made this case into a Star Chamber on whether White should be blamed for everything that went wrong at the State Police drug control bunker,” he added.

Reilly spokeswoman Beth Stone said prosecutors respect the jury’s verdicts.

“This was a lengthy trial with a lot of complex evidence,” she said. “At the same time, we are disappointed we don’t have a verdict on the indictments that reflect the serious misconduct of a police officer.”

Stone said there was no clear timetable for retrying White on the remaining charges, which carried a minimum of 15 years in prison.

During White’s trial, prosecutors claimed White was able to steal the drugs from the State Police Narcotics Inspection Unit due to lax supervision. George argued that the unit’s shoddy record-keeping made it impossible to prove White’s guilt.
