    Details of Disappearance

    Mero was last seen in McCloud, California on February 15, 1997. She was apparently last seen on the front porch the residence of Ed Henline Sr. and his wife Deborah. The couple lived on east Minnesota Avenue in McCloud at the time and Mero formerly lived at their home with her boyfriend, Ed Henline Jr. She has never been seen again.

    Mero was not reported as a missing person to law enforcement until October 1997, eight months after she disappeared. Authorities and her parents initially believed she had left of her own accord, as she had a warrant out for her arrest. But as months passed with no indication of Mero's whereabouts, the police and her family became concerned for her welfare. She was separated from her husband at the time of her disappearance, and her only income was $700 a month in disability payments.

    Another young woman, Hannah Zaccaglini, also vanished from the same locale as Mero in February 1997, four months after Mero's disappearance. The Henlines were questioned in both cases and their home was searched by law enforcement, but the couple has never been connected to either disappearance. Authorities maintain that the Henlines remain possible suspects in the cases, however. The couple was accused of writing fraudulent checks on Mero's bank account after she disappeared. They were also arrested on drug charges in 1999.

    Another possible suspect in both Zaccaglini and Mero's cases is Wesley Howard Shermantine. A photo of Shermantine is posted below this case summary. He was convicted in 2001 of four murders in California, including the presumed deaths of Chevelle Wheeler in 1985 and Cynthia Vanderheiden in 1998. It is not known if Shermantine is involved in either Zaccaglini or Mero's disappearances. Both cases remain unsolved.
