Crime - Sacto 911

Sacramento County DA making a name for groundbreaking DNA investigations

Sacramento County District Attorney Anne Marie Schubert and her investigative partners are breaking new ground by the month, using DNA-sleuthing to solve old crimes.

Suspected serial rapist Mark Manteuffel’s arrest last Friday marked the third time in 14 months that local law enforcement officials have used DNA matches from publicly available ancestry companies to solve decades-old violent crimes.

FBI investigators, acting on a tip from Sacramento law enforcement, got Manteuffel’s DNA from an undisclosed item he left behind at a restaurant, Sacramento Police Department Chief Daniel Hahn said at a press conference Monday.

Schubert’s office had identified him as a suspect through a genealogical website similar to that used in two other arrests, one of which merited the “DNA Hit of the Year” award from Gordon Thomas Honeywell Governmental Affairs.

The list of recent arrests represents a who’s who of major sexual-assault crime solving:
