A North Lawndale man was charged with first-degree murder in the fatal shooting of a 19-year-old woman in a vehicle Thursday in the New City neighborhood, Chicago police announced Saturday.  Trevon Smith, 18, was arrested at 6:10 p.m. Thursday in the 4800 block of South Seeley Avenue after police said he shot and killed Belinda Fuentes-Herrera about 15 minutes earlier in the 2000 block of West 47th Street, a short distance away.  Fuentes-Herrera was in a vehicle traveling through an alley when Smith allegedly approached her, police previously said. Smith then pulled out a gun and fired at Fuentes-Herrera, striking her in the face and chest.  She was taken to Mount Sinai Hospital in critical condition and pronounced dead at 8:01 p.m, according to the Cook County medical examiner’s office, which ruled her death a homicide.  Police said they recovered a firearm at the scene but did not reveal a suspected motive for the shooting.  Smith is scheduled to appear in court Sunday afternoon for a detention hearing.
