link A man repeatedly stabbed his toddler and estranged wife along an interstate while horrified people watched from their cars in rush-hour traffic Friday night, police and witnesses said. The 2-year-old girl was in a car with her parents when her father started stabbing his wife with a kitchen knife along Interstate 110 near the Governor's Mansion, said Cpl. L'Jean McKneely, a Baton Rouge Police spokesman. When the 26-year-old woman got out and ran for help from an East Baton Rouge Parish sheriff's deputy in squad car just ahead of them, her husband stabbed his daughter, McKneely said. 'He kept stabbing her until the knife was stuck in her head,' witness Gloria Spears told WAFB-TV.
