Michael Valva's attorneys file notice of appeal
Michael Valva's attorneys tell News 12 they have filed a notice of appeal.
The former NYPD officer was convicted in November of murdering his 8-year-old son Thomas Valva.
Prosecutors say Michael Valva forced his two sons - Thomas Valva and Anthony Valva - to sleep in an unheated garage for months, starved them and subjected them to physical and emotional abuse.
The 43-year-old father was sentenced to 25 years to life.
News 12 was also told that he is currently serving his sentence at an upstate prison in Elmira.
