The Ramsey County sheriff's office water patrol unit went back to Keller Lake in Maplewood Tuesday afternoon to continue the search effort for Kira Trevino.
The Star Tribune reports the crew arrived on the lake around 1:30 p.m., drilled holes in the ice near a previously searched area and left about an hour later. St. Paul police say the holes will help cadaver dogs pick up a scent, if any.
FOX 9 says officials plan to bring out search dogs to check for Trevino's scent on Wednesday.
The water patrol waded through a creek at the southern end of Keller Lake in Maplewood on Monday. The newspaper also noted that sheriff's deputies found a jacket on the bank of the creek. Over the weekend, volunteers found a half dozen "items of interest" in the park, but police could not confirm if any are related to the murder case.
On Friday, the Ramsey County Attorney's Office filed an amended criminal complaint that states a plastic bag found in Keller Regional Park contained a bloody pillow, pillow case, sports bra, shirt and sponge. An analysis revealed the blood matched Kira's DNA.
Kira Trevino, 30, is presumed dead by authorities after blood was found in her car and at the Trevino’s home. Her husband, 39-year-old Jeffery Trevino, faces charges of second-degree murder.
