Deandre Davoughn Washington, brother of Teen Mom star Ashley Jones, was found dead at a train station outside of San Francisco on Dec. 17. Washington, 32, was the oldest child for his mother Pastor Tea, The U.S. Sun reports.

The grieving mother expressed her sorrow on social media.

“I’m outdone and broken to the core,” she wrote, sharing a photo of her son on Instagram. “My firstborn child Deandre has passed away. My soul has been ripped from my body. Please keep us in prayers.”

Washington kept a low profile despite his family’s celebrity status. The 32-year-old didn’t have an Instagram profile and he was never featured on Teen Mom 2.

According to The Sun, police said “medical personnel responded to the station regarding an unresponsive adult male” at 5:47 a.m.

“Medical personnel declared the male deceased,” police told the publication. “There is no foul play suspected.”

Officials said the investigation is continuing as medical examiners are awaiting the results of the toxicology report
