Closings begin in case of mom accused of killing son in 1991

MIAMI - FEBRUARY 02: A judges gavel rests on top of a desk in the courtroom of the newly opened Black Police Precinct and Courthouse Museum February 3, 2009 in Miami, Florida. The museum is located in the only known structure in the nation that was designed, devoted to and operated as a separate station house and municipal court for African-Americans. In September 1944, the first black patrolmen were sworn in as emergency policemen to enforce the law in what was then called the "Central Negro District." The precinct building opened in May 1950 to provide a station house for the black policemen and a courtroom for black judges in which to adjudicate black defendants. The building operated from 1950 until its closing in 1963.  (Photo by Joe Raedle/Getty Images)

Closing arguments have started in the trial of a Florida woman charged with killing her 5-year-old son in New Jersey in 1991.

Prosecutors have presented evidence they say proves Michelle Lodzinski was lying when she told authorities Timmy Wiltsey disappeared while they were at a carnival.

They say a blanket found near the boy's body several months later came from Lodzinski's apartment.

Lodzinski's lawyer has focused on the fact that no forensic evidence directly ties the boy or his mother to the blanket.

Former law enforcement officials testified Lodzinski offered conflicting accounts of the boy's disappearance.

Long a suspect, Lodzinski was arrested near her home in Port St. Lucie, Florida, in 2014 after a former baby sitter identified the blanket.

The trial began in mid-March.
