Bodies of two Indian students have been recovered after they went missing at a lake in the US state of Indiana, according to media reports.

Siddhant Shah, 19, and Aryan Vaidya, 20, went swimming at Monroe Lake, roughly 64 miles southwest of downtown Indianapolis, with a group of friends on April 15 but didn’t resurface, the USA Today newspaper reported.

Both students attended Indiana University’s Kelley School of Business. They were missing in the water since April 15.

The bodies were located and recovered by search crews on April 18 east of the Paynetown Marina in 18 feet of water. The two were boating on a pontoon when their group anchored to swim in the lake, which is 10,750 acres and 35-40 feet deep.

“When both men did not resurface, friends tried to help but were unsuccessful,” the Indiana Department of Natural Resources said in a news release.

One of the men had been struggling in the water when others jumped in to help, USA Today cited Lt. Angela Goldman, a Department of Natural Resources representative as saying.

“The entire Sycamore community is heartbroken by this sudden loss. Aryan was very involved during his time at Sycamore, including as a member of the student council and DECA,” WLWT television station, affiliated with NBC, reported.
