A 14-year-old girl strangled by her father was carrying his baby, prosecutors revealed yesterday. Miguel Matias, 36, has confessed to killing his daughter because he caught the teen typing "sexy things" on her computer, reports the New York Daily News. Authorities have now discovered that DNA taken from girl's fetus matches her father's. Her naked body was tossed in a boiler in the family's apartment building. Matias has now been charged with rape and incest, in addition to murder.
