Imprisoned murderer Gene T. Meyer was convicted yesterday of solicitation for murder, the second time in less than three months he has been found guilty of the crime.

A Baltimore city jury convicted Meyer, 30, of trying to hire an undercover officer posing as a priest to kill state policeman Frank Mazzone. Mazzone's testimony last April led to Meyer's conviction in April on nearly identical murder-for-hire charges.

Meyer was convicted in 1978 for the butcher knife slaying of a friend's wife and his four-month-old daughter in their Bowie home. The day he was sentenced to life imprisonment for the crime, prosecutors revealed that while in pretrial detention Meyer solicited Mazzone -- then posing as an attorney -- to kill his own wife and three men.

After hearing tape recordings of conversations between Mazzone and Meyer, a Prince George's county jury in April found Meyer guilty. The trial judge added 80 years to Meyer's murder sentence.

According to testimony in the Baltimore trial, Meyer, while in prison, offered $15,000 to another undercover officer in January 1979 to have Mazzone killed. Meyer ultimately paid $10,000 to a fellow inmate who had agreed to find a professional assassin.
