(WMC-TV) - Maurice Brown, Sr. was escorted into court by two jailers. He seemed calm and emotionless during his video arraignment Monday.
"He was advised of the new charges, which in this case is murder in the first degree, as well as resisting official detention," said Prosecutor Jennifer Nichols.
The resisting official detention charge came when Brown fought with jailers over getting his fingerprints.
"Last week, I was asked whether there would be additional charges added and, of course, I couldn't comment on that because I didn't know. The police continued their investigation and did find, obviously, additional evidence," said Nichols.
One week ago, Brown told police his 3-year-old son went missing while he was asleep. When he woke up, he said his son was gone.
Little Maurice Brown Jr. was found dead in a dumpster two days later.
Police found blood all over the bathroom of the family's apartment. The medical examiner determined the boy died of blunt force trauma.
"The new charge of murder resulted from finding the body and getting a cause of death," said Nichols.
Maurice Brown, Sr. now sits in jail without bond. He is charged with 1st degree murder in connection with the death of his 3-year-old son.
