SELMA, Ala. (AP) -- Authorities say a man charged in the deaths of 9-year-old twins and their 73-year-old baby sitter has been taken into custody.

Dallas County District Attorney Michael Jackson says that 22-year-old Deandra Marquis Lee was caught in Selma Saturday morning. Jackson says the arrest came after authorities got a tip called in to a tip line set up by the Alabama Bureau of Investigation.

Lee is wanted in the slayings of twins Jordan Dejerinett and his sister Taylor, plus 73-year-old Jack Mac Girdner. Authorities say Girdner was a retired anesthesiologist who sometimes babysat the children.

The bodies of all three were found Tuesday in rural Lowndes County. Police say they were shot.

The search for Lee was concentrated in Dallas County, where he was acquitted in a double murder last year.
