An autopsy later revealed the baby died of asphyxia.
Bean drank at least six shots of tequila with a friend the night of her son's death, resulting in a blood-alcohol level of .190, according to court papers obtained by Fox 13. The mom was apparently starting to breastfeed her son when she dozed off, the news station reported.
“This isn’t a co-sleeping issue, this is an issue pertaining to an adult who was intoxicated to the point they are incapable of taking care of their 3-week-old,” Lancaster County Sheriff Capt. Ben Houchin told Fox 13.
Investigators believe Bean "knowingly and intentionally placed her infant son in a situation that endangered his life," police said.
If convicted, Bean could face up to 3 years in prison, 18 months post-release supervision or a $10,000 fine. According to Fox 13, Bean was also pulled over by local police for driving under the influence after her son's death, though those charges are still pending.
