Forensic Files

Up next, a well-known business owner is

brutally attacked at work.

There was a lot of blood on the floor, on the walls, on the

door.

Is it the work of a disgruntled employee...

No one trusted him.

He leaves due to stress.

Or a robbery gone wrong?

I'd given her $1,000 the night she was killed.

That $1,000 was never found.

A witness comes forward with a possible motive.

She made me promise that if anything happened to her, I'd go

immediately to the police.

The evidence answers some questions and

raises many more.

It didn't look planned.

He just, basically, probably snapped.

For years, George Hansen and

Mary Ann clibbery ran zullo's remodeling as business

partners in loves park, Illinois.

And they were quite a pair.

Their homespun television commercials helped make their

business a success.

At al zullo's, the "don't move, improve" folks...

Where one call does it all.

Mary Ann ran the finance and business side.

George ran the construction crew... maintenance, buying the

products, that sort of thing.

By 2004, Mary Ann told her partner she wanted to

retire.

Very nice person.

Very kind.

She'd do anything for anybody.

She wanted to start enjoying life a little bit, to get the

fruits of her labor.

A few days before the Christmas holiday, after

everyone else had left, Mary Ann stayed late to go over the

books.

As she was about to lock up the office to leave, she was

viciously attacked.

The next morning, her partner, George Hansen, and another

employee found Mary Ann's body when they arrived for work.

I saw all the blood around Mary Ann.

I'd never seen a dead body before.

And nothing that horrible.

Paramedics pronounced her dead at the

scene.

Every morning, you always got a... I always went into her

office to tell her to have a good day.

And, of course, that's what you got back.

And that's the last time I spoke to her.

She had substantial head injuries, and the pathologist

determined that she had suffered at least three blows to the back

of her head.

Crime scene technicians found some unusual

clues.

There was fresh blood on top of coagulated blood, which meant

there were two separate altercations.

I could tell that she was hit in the hallway first, at least

twice.

And when she went down, she went down for a minimum of 15 minutes

before he knelt on her back and beat her at least two more

times.

Made you question why that person would go back to her and

beat her more.

Mary Ann's purse was missing... an indication the

motive might have been robbery.

But nothing else had been taken from the office.

We would expect anything of real value that individuals

could carry would be missing.

Nothing was missing from the business.

Mary Ann was a 69-year-old widow, the mother of

five grown children.

I'm visually impaired.

She was...

My eyes...

She was my love...

And she was my life.

We had things to do.

We weren't two old people sitting, watching the clock go

around.

In a search for suspects, investigators learned

that the company recently fired an employee, Kevin Doyle, and

his dislike for Mary Ann was well-known.

No one trusted him, including zullo employees.

He was a former employee of al zullo's.

He leaves due to stress, somewhat maybe of a nervous

breakdown.

Doyle had a motive, and he still had keys to the

building, making him...

The prime suspect.

Hi, I'm Mary Ann and this is George and we're from al zullo

remodeling specialists.

Al zullo's remodeling was an institution in

loves park, Illinois.

Al zullo remodeling has been a part of making your house a

home.

Mary Ann was in some of the print advertising very early on

in the business.

Kind of doing this vanna white thing with the kitchen cabinets.

And Mary Ann clibbery was well-known

in the community for her generosity.

She would advance employees salary... out of her own pocket,

not the company money.

Investigators were convinced Mary Ann was killed by

a client or a co-worker.

Had to be somebody who was somewhat familiar with the

layout of the business.

The investigation centered on a disgruntled

ex-employee, Kevin Doyle.

He was not a reputable person.

I believe that he was a lot of talk, but couldn't perform.

I believe he said things that weren't accurate, and I believe

that he was not to be trusted.

When questioned, Doyle said he was at home sick

at the time of the murder.

But there was no one to back up his story.

Kevin Doyle had no criminal record, but the day after the

murder, he did something very strange.

Kevin shows up and offers his assistance to the family and how

he himself can keep that business afloat.

We're thinking, "okay, we have a suspect here."

You know, you hear so often the "over-cooperative witness," so

to speak.

Well, that was Kevin.

Police also learned that Mary Ann and her business

partner, George Hansen, never got along.

It is always a challenge between the two because their

personalities are so much different, they're always in

conflict.

She was always very elegant, talked very well, carried

herself very well.

He did not appear to be what I would call a strong, ethical,

honest person.

They were business partners, and they had worked together for

many, many years.

She didn't realize that he was angry over the fact that

al zullo had made her an equal partner to the business when he

died.

George denied there were problems and said his

relationship with Mary Ann was a good one.

When you have a business relationship, just like a

marriage, you got to get along.

If you don't get along, break it off.

And we got along great.

When questioned by police, George said he had an

alibi for the time of the murder.

He had gone to have drinks with his wife, then he took his

daughter to some driving school and had gone to a tanning salon

and, I believe, maybe at that point he finally went home.

Then, the day after the murder, there was an

unexpected development.

A local resident called police to report seeing a black

garbage bag on top of the ice on the rock river, which was

5 miles from the murder scene.

What really brought it to their attention is, not too long

before that, there was a baby discovered in a garbage bag.

The fire department used a ladder truck to lift the

bag from the ice.

It was a substantial project.

Several men had to go down, over the river and the ice, which is

dangerous, and retrieve the bag.

Inside the black garbage bag was another plastic

bag, filled with a variety of items... a sweater, a hammer,

leather gloves, and a purse containing Mary Ann clibbery's

identification.

I think when they found that bag, that connected everything.

Apparently, the killer threw the bag from the

bridge, but missed the open water and it landed on the ice

instead.

If he'd looked over the bridge, he could have took two

or three steps and he had open water.

How stupid can you be?

The sweater in the bag was covered in blood.

There was blood spatter inside the right sleeve, which

goes along with the thought at the scene that it was a

right-handed person that hit her from behind.

Tests showed the blood was Mary Ann's.

Employees recognized the sweater right away.

It belonged to the original owner of the company, al zullo.

Mr. zullo had the sweater for many, many years, and it was

always in her office.

Other people put it on, too, when they got cold.

Scientists looked for areas on the sweater that

might contain skin cells.

I swabbed the collar of the sweater to determine the wearer

of the sweater.

Would these skin cells identify the killer?

Police had two suspects in the murder of

Mary Ann clibbery... her business partner, George Hansen,

and a disgruntled employee, Kevin Doyle.

Forensic testing of the bloody sweater found in the discarded

plastic bag with Mary Ann's personal belongings found skin

cells on the collar.

The skin cells provided a DNA profile.

When I analyzed the swabbing of the collar to determine the

wearer, it matched George Hansen's profile.

And it didn't match anybody else's profile.

But that didn't prove he was the killer.

The sweater belonged to the original business owner,
