Detroit - He was waiting at a bus stop in Burton, Mich., when a man approached.

The guy said he needed help with his vehicle.

It wasn't long before Antoine Jackson became the fifth victim of a man police say is a serial killer targeting men and stabbing them, some to death.

It was early July 12 when the 28-year-old Jackson was stabbed four times, said his aunt Priscilla VanSickle of Flint.

"He stabbed him in the eye, actually to the bone and he chipped a bone off in his head," she said Tuesday. "He really, basically, left him there to die."

But Jackson didn't die. He is one of 16 men believed to have been attacked by a man in the Flint area. Five have been killed.

The latest victim came forward Monday, giving authorities details of the attack.

Investigators also are looking into whether four attacks in Virginia and Toledo, Ohio, are connected to those in Flint.

Most of the men have been African American, and those attacked in the Flint area have ranged in age from 17 to 60.

"I put it in the Lord's hands," said Essie Abernathy, mother of Frank Kellybrew , 60, who was found dead July 30 in Flint Township. "The Lord says, 'Vengeance is mine,' so vengeance is up to him."

On Tuesday, a police task force released a timeline of the stabbings in the Flint area that began on May 24 with the slashing of a 31-year-old black man.

The next attack was on June 21. But the number began rising dramatically in July, with 10 stabbings in Flint and nearby towns, including two on July 30.

No stabbings believed to be related have occurred in Flint since Aug. 2. The next day, the first of three attacks in similar fashion happened in Leesburg, Va. The last attack that police say may be connected happened Saturday night in Toledo.

Leesburg police released a surveillance video Tuesday, showing a green, late model Chevy Blazer believed to be driven by the suspect. He is described as a muscular white man in his late 20s or early 30s, about 5-foot-11 to 6-foot-2, and weighing 180 to 210 pounds, with light-colored hair and usually wearing a cap.

Michigan State Police said Tuesday that a 26-year-old black man went to the State Police Flint Post on Monday and said he was attacked July 27.

The latest victim to come forward said that his attacker drove up, asked for help, attacked, stabbed repeatedly and then drove off.

Stephanie Ward wouldn't be surprised if a similar situation occurred before her brother, Arnold Minor, was stabbed to death Aug. 2.

The 44-year-old Flint resident said her big brother, 49, always helped others.

She said the family had all gathered at another brother's house for dinner. Afterward, she dropped Minor off at her mother's house. At some point, Minor, who didn't have a car, left to walk several miles home.

He wasn't even a mile from home when he was attacked and left in the street.

A passerby called 911, Ward said.

"He thought everybody was friendly," she said of her brother. "Everybody's not friendly."

Meanwhile, police in Toledo said Tuesday they had no new information about the stabbing of church custodian Anthony "Tony" Leno, 59, on Saturday night by a man who resembles the Flint killer's description and reportedly drove an older model green Chevy Blazer.

Toledo police are investigating whether that case is connected to the Flint stabbings.
