ST. PAUL (AP) — A scientist with the Minnesota Bureau of Criminal Apprehension says suspected blood spots from a missing St. Paul woman's home and car matched her DNA.

McKenzie Anderson testified Thursday at the murder trial of 39-year-old Jeffery Trevino. Trevino is accused of killing his wife, 30-year-old Kira Steger. Steger was last seen alive Feb. 21, and her body was recovered from the Mississippi River in May.

Anderson told the court that several spots of suspected blood from the couple's master bedroom, home and Steger's car trunk matched Steger's DNA.

Under cross-examination, defense attorney John Conard attempted to cast doubt about the credibility of some DNA results.

The prosecution is expected to call its last witness Friday. Jurors could begin deliberating the case Tuesday.
