National Digest: DNA helps in N.Y. cold case from 1991 In a dramatic break in a cold case more than two decades old, investigators used DNA to identify the mother of a dead child known only as Baby Hope, police said Tuesday. The New York Police Department received a tip from someone after a publicity push during the summer, police officials said. The tip led to the woman, whose name was being withheld amid a homicide investigation. The case dates to July 23, 1991, when a road worker smelled something rotting and discovered the girl's remains inside a picnic cooler along the Henry Hudson Parkway. The body of the girl, believed to be 3 to 5 years old, was unclothed and malnourished and showed signs of possible sex abuse. Her body was exhumed in 2007 for DNA testing, but none could be extracted because of its poor condition. After a second attempt was made in 2011 using better technology on bone material, a DNA profile was developed, police said. Navajo Nation to stop wild horse roundups After talks with former New Mexico governor Bill Richardson (D), the Navajo Nation says it will end its wild horse roundups and reverse its public support for a return to domestic horse slaughter. Navajo Nation President Ben Shelly said Tuesday that he met with Richardson during the weekend and that they agreed to work together to find more long-term and humane solutions to the horse overpopulation problem. Richardson and actor Robert Redford created the Foundation to Protect New Mexico Wildlife this summer to fight efforts by a Roswell, N.M., company and others to slaughter horses. Shortly after the foundation was announced, the Navajo Nation came out in support of the company, saying it has 75,000 feral horses drinking wells dry and causing ecological damage to the drought-stricken range.
