The investigation into a fiery crash that killed five people and badly burned a young boy in January near Windsor has taken longer than first expected, but could be turned over to the district attorney in the next few weeks, the CHP said.

The complex investigation, relying on multiple agencies, has encountered unexpected delays but ?is in the final stages,? CHP Officer Barbara Upham said Friday. ?It?s currently going through the review process.?

In question is whether charges will be sought against Ryan Karr, the driver of a Mitsubishi coupe that smashed into the back of a Honda Civic on Highway 101 during the late-afternoon Friday commute on Jan. 19.

Prosecutors in the spring said Karr may face vehicular manslaughter charges in the crash, which left five people dead and injured 5-year-old Christian Flores Carlos.

In addition to his mother, 23-year-old Edith Carlos Medina, the Windsor boy lost his grandmother, Maria Lopez Camacho, 54; brother, Fernando Flores Carlos, 7; aunt Almadelia Mendera-Basurto, 16, all of Windsor; and aunt Carmina Solorio, 23, of Mexico.
