Casey Kennedy, 20, says she knew Boyd since 7th grade through First United Methodist Church. Boyd was active in the youth community at the church, according to First United Methodist.
Kennedy describes Boyd as sweet, intelligent and brother-figure.
"I don't really call anyone a brother but when I met him, he became that way," Kennedy says. "He just made everyone smile."
On Tuesday morning, Kennedy created a Facebook page called "Prayers for Brendan Boyd." As of Wednesday, the page has reached over 100 likes, Kennedy says.
She's been gathering and saving photos of Boyd to make collages and posting them on Facebook.
"I've been getting good feedback so far," Kennedy adds. "We have had someone from Illinois like the page."
College Station Police say a man matching Boyd's description was seen at a convenience store in Laredo on Christmas Day. It is the same store where Boyd's car was recently found and towed from. Boyd was expected to be in Abilene on Christmas but never showed up.
