Friends and family gathered Tuesday for the funeral of Jane Bashara, the Michigan mom strangled to death near Grosse Pointe Park last week.

But for one family friend, just paying his respects wasn't enough.

Hours after police discovered the body of 56-year-old Bashara in her SUV Jan. 25, people living on Detroit's east side reported a strange man known only as Jim looking to solve her murder, and offering a $10,000 reward to anyone who could help him find her killer.

Mystery Man Interrogates Detroit Neighborhood

Around 4:15 p.m., according to ABC News, a white male who said he was from Grosse Pointe began going around the Detroit neighborhood where Bashara was found, knocking on doors.

He asked anyone who answered if they knew any information about what had happened to Jane Bashara in the alley, and said he had a substantial reward for anyone who could help.

One woman, who wished to remain anonymous because the exchange made her uncomfortable, said Jim came to her door the afternoon that Bashara's body was discovered.

She described him as a white man driving a white SUV, with a receding hairline, salt-and-pepper hair, and wearing a light beige jacket.

The woman had noticed Bashara's car when she woke up in the morning, but hadn't seen anything suspicious the night before. She remembered her dog being spooked by something in the alley, but that was it.

He said, Well ma'am, if you know and can lead anyone to the arrest and conviction of the person that killed my friend, you have a ten thousand dollar reward, the neighbor told ABC.

He left behind a scrap of paper with his first name and phone number on

Fox News reports that several other people in the Detroit, Mich. neighborhood were approached by the mystery man.

'My whole family told me to be very careful.'

But who is Jim, the man looking for answers in Jane Bashara's murder?

According to Fox, sources report the man's story is true. He is a family friend of Jane and her husband Bob Bashara, and was trying to help with the investigation.

The woman whose dog was spooked by Jane Bashara's car, however, remains uneasy about the encounter.

I sat and I thought about it, and my whole family told me to be very careful, she told ABC. Because there's nothing on television about a reward.

The mystery man, meanwhile, has reportedly already gone to the Grosse Pointe Park police.

No more information has been divulged as to his identity, but those approached say the paper on which he wrote his name and number bore the Grosse Pointe Academy logo on one side.

Bob Bashara Under Scrutiny

Investigators, meanwhile, are remaining tight-lipped on any leads in the Jane Bashara murder case.

Local 4 News reports that police have evidence suggesting that Jane's husband Bob, already a person of interest in her death, may have been with her in downtown Detroit on Tuesday night.

The station also reports that investigators believe her killer didn't act alone. Rumors are floating that an accomplice helped stage the crime scene as a botched robbery.

Sources also claim that Bob Bashara failed a recent lie detector test, though police have yet to comment on the results.

Funeral services for the Michigan mother began at Grosse Pointe Memorial Church at 10:30 a.m.
