MADISON, Wis. -

An arrest has been made in a Madison homicide case, according to Madison police.

Police said at a news conference on Wednesday that Tyrone Isaac Jr., 27, of Madison, turned himself in to a sheriff's office in a suburb of Denver on Tuesday.

Police believe the entire incident started in downtown Madison near the parking garage on North Francis Street around 2:15 a.m. Sunday.

Police said when they got to the parking garage they found a large disturbance involving several dozen people. One hour later and 3 miles south, police said several of the same individuals were involved in the homicide that took place on Badger Road.

Officers were called to the area around 3:30 a.m. Saturday, after a report of shots fired.

“The investigation shows more than one firearm was used at the scene on West Badger Road,” MPD Capt. Joe Balles said. “We are still looking to speak to several persons we know were present on West Badger Road at the time of the homicide.”

Madison police said Isaac's car was spotted on a surveillance camera fleeing the scene of the shooting, and a short time later the silver Pontiac was found on the west side with several bullet holes in it.

Officers in Dubuque, Iowa, learned Isaac had been treated for a gunshot wound to the leg on Sunday, according to police. Officers said Isaac then boarded a bus for Denver. Police in Denver were told to look for him. Police said Isaac knew he was being sought by police and turned himself in.

A silver Pontiac found on the west side following the shooting had bullet holes in it, according to police.

Darren L. Goodwan, 25, of Madison was found on West Badger Road early Saturday morning suffering from a gunshot wound. He was taken to an area hospital, but later died from his injuries.

Isaac is being held in Colorado awaiting extradition. Madison detectives are there to interview him.
A second person was injured in the incident. Those injuries were not life-threatening and were likely not caused by gunfire.

Police are stilling investigating the circumstances surrounding the shooting, but Madison Police Chief Mike Koval said the problem is bigger than this one incident.

"Some in our community would say that this is an issue that we would ascribe to Milwaukee, 72 miles to the east. To which I say, 'Get your head out of the sand. Violence is right here in Madison," Koval said.

Koval said there were at least four incidents involving the discharging of firearms in Madison in the days leading up to the Badger Road homicide. He also said on virtually every night officers are called to respond to either a weapon being used in a crime or shots being fired.

“We have gun violence erupting throughout this city, and it is growing at an alarming rate,” Koval said.
