WYOMING, MI -- A man possibly tied to a fireworks store blaze also is believed to have broken into a nearby home, where a teen awoke to find a man with a towel over his shoulder and a jug of orange juice in his hand.

Juan "Johnny" Covarrubias, 19, said he was sleeping on a couch in his family's Oriole Avenue home about 8 a.m. Tuesday, July 5 when he awoke to find a man standing nearby.

The man, who appeared to have showered and had a towel over his shoulder, grabbed Covarrrubias' car keys from the floor next to the couch.

"He said 'I'm going to need these,'" a bewildered Covarrubias said.

The teen only found out later that the man is being investigated for a suspicious fire at GS Fireworks on 44th Street near Burlingame Avenue about 6:30 a.m.

He also set Covarrubias's home on fire before stealing the teen's car.

At the time, when the teen awoke, he thought the man was a drywall contractor who was supposed to work on the house that day.

He figured he needed the keys to his Volkswagen Jetta to temporarily move it for unloading materials.

In fact, the man told Covarrubias that he was, indeed, the drywall contractor when the teen asked him.

But Covarrubias quickly became suspicious after looking at the man -- he had no shirt with a towel over his shoulder and a jug of orange juice in his hand.

"He took a shower and he had orange juice in his hand," an incredulous Covarrubias said later Tuesday morning, looking back at the incident.

The teen then headed outside with the man. The person was now carrying a plastic garbage bag with clothes inside, he said.

It was then that the man said 'You can come with me but I don't think that would be a good idea.'

"I guess he thought I was a friend or something," Covarrubias said.

Covarrubias then knew something wasn't right and headed to a neighbor's house to call 911. He saw the man re-enter his family's home.

When he returned and the police had arrived, there was smoke pouring from the home and his Jetta was gone.

Covarrubias' family had moved into the Oriole Avenue home less than two weeks ago.

The extent of damage to the house was not immediately clear.
