GRAND RAPIDS, MI - A Lowell Township man took an 18-month-old girl to a motel room where he tied her to a bed and video recorded himself having sex with the child and engaging in unimaginable, depraved degradation of the toddler, according to police.

Eric Devin Masters, 28, is charged with four counts of criminal sexual conduct stemming from the alleged assault of the baby in June of 2012 at the former Motel 6 on 76th Street SW in Byron Township.

The assault was discovered when FBI agents were investigating Masters for a series of sex crimes throughout the state.

An agent said one of the videos discovered on Master's computer showed the acts against the child by a man with the same tattoos found on Masters.

The graphic details of the assault were included in a probable cause affidavit filed in Kent County District Court.

Masters pleaded guilty in U.S. District Court in Grand Rapids to multiple counts of sexual exploitation of a child and producing child pornography that carry a sentence of between 15 years and life.

The government alleges the crimes began in 2011 and occurred in Ionia, Kent, Muskegon, Grand Traverse and Mackinac counties. He is scheduled to be sentenced March 18 before Judge Robert Bell.

Masters also awaits sentencing after pleaded no contest to third-degree criminal-sexual conduct with a 13-year-old in Muskegon County Circuit Court.

Last year, Masters was sentenced to 36 days in jail and five years on probation after he pleaded no contest in Ionia County Circuit Court to second-degree criminal-sexual conduct, state police records showed.

Masters appeared briefly Monday, Feb. 23, in Kent County District Court before Judge Jeffrey O'Hara where the defendant waived a probable cause hearing on three counts of first-degree criminal sexual conduct and one count of second-degree criminal sexual conduct.

Masters will be tried in Kent County before Circuit Court Judge Mark Trusock in between hearings in federal court and Muskegon County, where he has been held for more than a year on a $250,000 bond, according to court records.

First-degree criminal sexual conduct convictions can be sentenced consecutively as was done last week in the case of Michael Emory who pleaded guilty to raping a 1-year-old child.
