SPRINGFIELD — Eugenio Negron, 36, has been indicted for 21 crimes by a Hampden Superior Court grand jury.

Negron, of Springfield, was arrested July 3 following a wild chase through the downtown that ended with a crash on an on-ramp to Interstate 91.

He was indicted Wednesday for trafficking oxycodone in the amount of 100 to 200 grams; possession of heroin with intent to distribute (subsequent offense), possession of cocaine with intent to distribute (subsequent offense); two counts of distribution of marijuana (subsequent offense); and violation of a drug free school zone.

Negron is charged with five counts of assault and battery with a dangerous weapon and a count each of reckless operation of a motor vehicle, leaving the scene of a property damage accident and driving with a suspended license (subsequent offense).

He is also charged with possession of a firearm during commission of a felony, illegal possession of a firearm and ammunition, improper storage of a firearm and possessing a firearm with a defaced serial number.

The final charges are resisting arrest and refusal of a motor vehicle operator to identify himself.

According to information from Springfield police at the time of the arrest, Negron and his passenger, 30-year-old Edgardo Cruz, threw bags of heroin and marijuana out the windows and ran numerous red lights as they fled. They hit speeds in excess of 65 mph, even with a blown left rear tire, as they ultimately headed north on East Columbus Avenue and onto the on-ramp.

Detective Edward Kalish was able to pass the suspect vehicle on the on-ramp and slowed the pursuit by not allowing it to pass. Detective Dean Fay, who filed the police report, wrote that he then pulled alongside the suspect car.

Negron swerved to the left and then violently to the right as he attempted to pass Kalish, according to Fay’s report, which was filed in support of court documents.

Negron lost control because of the flat tire, and slammed violently into Fay’s vehicle and spun out on the on-ramp. That section of the on-ramp is near Exit 9 which feeds onto the North End Bridge.

At their District Court arraignments, Negron was ordered held in lieu of $100,000 cash bail and Cruz $5,000 cash bail. The date for the Superior Court arraignment has not been set.

The chase began shortly after 10 a.m. when the detectives, following the suspects' gray Infiniti as it headed west on State Street, attempted to box it in at a red light at Chestnut Street.

As Fay approached badge-in-hand, Negron put the Infiniti in reverse, accelerated wildly and rammed detective Gregg Bigda’s vehicle, the report states. Negron then jumped the curb, which is presumably where he damaged the tire, and drove across the grass at Quadrangle Park and onto Chestnut Street, according to the police report.

The whole thing began when detectives initially spotted the suspects that morning as they approached 390-392 Walnut St. to execute search warrants pertaining to Negron's alleged heroin sales.

Detectives saw Negron arrive at 392 Walnut St. in the Infiniti and then leave less than two minutes later. They then followed him to State and Chestnut, where they attempted to box him in.

After the crash and arrests, detectives executed the search warrants at 390 and 392 Walnut St. Detectives ultimately recovered $73,256 in cash, a .45 caliber Hi-Point handgun with eight rounds, 1,099 grams of raw heroin, a bag of cocaine and five bags of marijuana,

Cruz, of West Springfield, was indicted for possession of heroin with intent to distribute and possession of marijuana with intent to distribute, both as a subsequent offender.
