Authorities say multiple people may have been involved in the deadly shootings of three people in rural central Kansas.

The Wichita Eagle (http://bit.ly/2feq5uV) reports that Harvey County Sheriff T. Walton wouldn’t elaborate Wednesday or say how many people may have been involved in the killings. He discussed the possibility of multiple suspects a couple of hours after authorities said a 35-year-old man is being sought for questioning.

The victims have been identified as 33-year-old Travis Street, 37-year-old Angela Graevs and the couple’s Newton friend, 52-year-old Richard Prouty. Their bodies and the couple’s unharmed 18-month-old were found Sunday outside a home in a rural area south of Moundridge. The couple was facing drug and child endangerment charges.

Harvey County Attorney David Yoder says the motive appears to be drug-related.
