Howard Milner is a resident of the Terra Nova colony. Howard could enter Terra Nova because he won the lottery. He never had been in a romatic relationship, but when word came out that he had won the lottery, many women became interested in him. Before the Pilgrimage, Howard married with Rebecca, so she could join him to Terra Nova.
Howard admitted to killing a security team member, Foster, because Foster had been having an affair with Howard's wife, Rebecca Milner. He had been trying to cover for Rebecca, thinking she was the one that had killed Foster, when, in fact, she had not. Howard was banished from the colony into the jungle for a short time, but his name was eventually cleared when it was discovered that Foster's true killer was another officer named Curran, who was then banished from the colony.
