A central Florida prison inmate has been sentenced to another 43 years for killing his cellmate for whining too much.

A Lake County judge sentenced 23-year-old Phillip Adams last month. He had previously pleaded guilty to second-degree murder in a deal with prosecutors to avoid the death penalty.

Authorities say Adams was sharing a cell at Lake Correctional Institution with 43-year-old Marc Rogers in July 2009 when Adams grew tired of listening to Rogers complain about his sentence. He was serving 25 years for fatally stabbing a housemate in Boynton Beach.

Authorities say Adams chewed the hem off a bed sheet and used it to strangle Rogers.

If not for the attack on Rogers, Adams would have completed his four-year sentence for lewd and lascivious molestation in October.
