RIVERSIDE, Calif. (AP) — A man and woman are accused of murdering their baby daughter in a Southern California trailer park, then putting her in a trash bag and driving her body around the country.

Jason Hann, convicted of killing the couple's other child in 1999, is now charged with murdering 2-month-old Montana in 2001 near Desert Hot Springs.

Hann pleaded not guilty Friday in Riverside County. The child's mother, Krissy Werntz, had already pleaded not guilty.

Prosecutors say Montana was killed in February 2001. The parents allegedly drove the body around the country before placing it in an Arkansas trailer. The body was discovered in 2002.

Hann was extradited from Kentucky, where he was serving time for killing his 6-week-old son in Vermont. The couple allegedly traveled with those remains for 18 months.
