Police: Missing boy's blood found in mom's trunk

COLUMBIA, S.C. (AP) -- Police say bloodstains found in the trunk of a Columbia mother's car belong to her missing son.

Officers discussed the evidence in the case against Zinah Jennings during a court hearing Monday.

Jennings' son, Amir, was 18 months old when he was last seen at the end of 2011. His mother has been charged with lying to police about where her son is.

Jennings is due to give birth to another child later this year.

It's up to a judge now to decide if the blanket on which the blood was found can be used in Jennings' trial, set for late August. Jennings' attorney says the blanket could prejudice a jury against Jennings, who is charged with illegal conduct toward a child.
