PORTLAND — A Portland man was sentenced Thursday in U.S. District Court to serve 25 years in prison for sexually exploiting a minor to make child pornography.

David Muise, 26, of 141 Cumberland Ave., had pleaded guilty to the charge on Jan. 29 and faced a sentence of up to 30 years in prison.

Judge Nancy Torresen also sentenced Muise to serve 20 years of supervised release following his prison term.

Muise used his cellphone camera to take a series of pornographic pictures of himself with a sleeping 4-year-old girl on Aug. 26, 2011. A search warrant executed at Muise’s residence in September 2012 revealed numerous sexually explicit photographs of the minor stored in multiple electronic devices, according to court records.

In 2012, he exchanged messages, files and photos over the Internet with Daniel Cobb, 37, of Rock Hill, S.C., according to court records.

After Muise’s arrest in October, Cobb was arrested in November at his home in South Carolina. Cobb faces the same charge as Muise and is accused of sending explicit pictures of his friend’s young daughters to Muise, according to court records.

Cobb pleaded not guilty in December and is currently scheduled for trial in U.S. District Court in Portland in June.
