SAN ANTONIO -

A man in his 40s was found dead around 10 a.m. Tuesday under an overpass on Interstate 10 near Woodlawn Avenue.

Police believe the victim was likely homeless and died due to spending the night exposed to sub-freezing weather.

It was out of a similarly sad situation that San Antonio Mission Ministries, or SAMMinistries, was born more than 30 years ago.

“A homeless person passed away on the ground of First Presbyterian Church in cold weather like this and the reverend who was the pastor at that time decided to start something,” said Navarra Williams, president & CEO of SAMMinistries. “He started a little shelter downtown in the basement of the church.”

Volunteers and employees of shelters throughout San Antonio often hit the streets this time of year to encourage the city’s homeless to escape the frigid weather, if only for a night, but some people refuse to seek shelter.

Williams emphasizes you do not have to be part of an organization to make a difference.

"One of the things you can do is put some blankets or coats you weren't going to be using in your trunk or back seat. If you see a person out there, you can pass that out to them,” Williams said.

If you are wary of handing out money to a homeless person, Williams suggests try food or a meal instead.

“Some people say, ‘Well, I'm not sure they're going to use my donation for food.’ Well, take some granola bars. You can give those out. Or you can give them a gift card to McDonald's or Whataburger because they’re everywhere in this city," said Williams.
