I-55 shooting

Court records linked Herndon's vehicle to another shooting that happened on Oct. 11 on Interstate-55.

Investigators say a vehicle that had just exited Interstate-55 on Bates Avenue had been hit with a single gunshot. Surveillance video showed a white SUV parked on the side of the interstate, which then fled immediately after the shooting.

Investigators say Herndon's white Buick was seen on surveillance video in the area 30 minutes before the shooting.

Court records say a single cartridge case found at the Interstate-55 scene had the same MaxxTech 23 7.62x39 headstamp as a cartridge case found at the scene of Wilson's murder.

The complaint says laboratory testing is still pending to determine if the ballistic evidence shows both cartridges were fired from the same gun.

Herndon's criminal history

In early 2001, Herndon was convicted of taking a vehicle without consent in Los Angeles, according to the complaint. In late 2005, Herndon was convicted in a Los Angeles court again on a charge of possession of a stolen vehicle. Then, in 2015, court records say he was convicted of receiving known stolen property and felony burglary, also in Los Angeles.

The Major Case Squad of Greater St. Louis says Herndon is currently from Arlington, Texas. It is unclear when Herndon moved from Los Angeles to Texas, or why he and his wife, Taiya Herndon, came to St. Louis.
